ADAM: A surface reflectance DAtabase for ESA's earth observation Missions.
The ADAM database has been created to address current and future mission requirements for a global surface
spectral Bi-directional reflectance Distribution Function (BRDF) database of the land, sea and permanent
ice sheets. The database covers the entire wavelength spectrum from 240-4000nm at 1nm spectral sampling
with a monthly time-step and at 0.1° x 0.1° spatial resolution.
The generated products are foreseen to be used by current and future passive and active Earth Observation
missions from Ultra Violet (UV), Visible (VIS), Near-Infra-Red (NIR) and Short-Wave-Infra-Red (SWIR) with
the scope of improving radiative transfer simulations and inversions and assessing new sensor performances.
The ADAM is a project funded by ESA General Studies Programme involving seven partners (contract number 102979)

About ADAM Products
ADAM Products
The objective of the ADAM project is to generate narrow-band Earth surface reflectances over
the spectral domain ranging from 240 nm to 4000 nm (with 1nm spectral resolution) and in any
observation geometry.
This has been achieved by producing:
a database of gridded monthly climatologies of:
normalized reflectances in the seven spectral bands of the MODIS instrument over land
chlorophyll concentration and wind speed over ocean
a stand-alone calculation package that allows the computation of the Earth surface reflectance in any
narrow-band / observation geometry using the datasets described above as input
ADAM Database
The main ADAM products consist of climatologies of:
Over ocean:
monthly chlorophyll concentration derived from SeaWiFS-OrbView-2 (1999-2009). It is used to compute the water
column
reflectance which shows large spectral variations but is significant only in the visible
spectral range.
monthly wind speed derived from SeaWinds-QuikSCAT (1999-2009). It is used to estimate the
sun-glint and
the foam contributions.
Over land:
monthly normalized surface reflectances in the 7 MODIS narrow spectral bands derived from FondsdeSol
processing chain of MOD09A1 product, derived from MODIS observations onboard Terra/Aqua.
uncertainty variance-covariance matrix for the 7 spectral bands associated to the normalized
surface reflectance. This is used by the spectral interpolation procedure to derive the spectral
variation of the uncertainty on the land surface reflectance.
The ADAM climatology over land is representative of year 2005. Sea ice pixels (masked in the
original MOD09A1 products) have been accounted for by a gap-filling approach relying on the
spatial-temporal distribution of sea ice coverage provided by the CryoClim
climatology for year 2005.
These products feed the ADAM calculation tools in the form of gridded data at 0.1° spatial resolution (Plate
Carree projection) and for 12 months, provided in NetCDF files.
ADAM Calculation Toolkit (API)
The ADAM calculation tools relies on the following principles:
over ocean, the surface reflectance is generated by the combination of (i) foam
reflectance, (ii) water column reflectance, and (iii) specular reflectance. The spectral
variation of the water column reflectance is mostly a function of the chlorophyll
concentration, at least over the open ocean (i.e. excluding coastal areas).The directional
variation of ocean reflectance is mostly a function of wind speed.
over land, the normalized reflectance in the seven narrow MODIS bands are first
extrapolated over the full spectral domain (0.24-4 µm). For soil/vegetation pixels, it is
performed using EOF (Empirical Orthogonal Functions) derived from spectral reflectance
measurements; The Ross-Li-Maignan kernel based BRDF model is then used to calculate the
reflectance spectrum in any observation geometry. A specific processing is applied for snow
covered surfaces: it relies on the ART model fitted to the MODIS normalized reflectances to
simulate the spectro-directional variations of snow reflectance.
Moreover, it is possible to calculate the uncertainty attached to land surface reflectance:
the calculation of the uncertainty related to the spectral extrapolation relies on the
variance covariance matrix of the reflectance values between the seven MODIS bands for each
0.1°x0.1° pixel; the calculation of the uncertainty related to the directional model is
performed using a priori estimates of the uncertainty on the directional parameters.

Database content
The main ADAM products consist of climatologies of:
Over land:
monthly normalized surface reflectances in the 7 MODIS narrow spectral bands. The climatology
derives from
FondsDeSols
processing chain using
MODIS MOD09A1 products at 500 m.
The reference year is 2005. Data from year 2006 have been used for gap filling over snow
for non-sunlit areas in winter. The sea ice
coverage is accounted for based on the CryoClim
climatology for year 2005 (osisaf-nh and osisaf-sh products); a gap-filling
procedure have been performed in order to represent
realistic surface reflectance in the seven MODIS bands for these snow cover pixels that were
masked in the original MOD09A1 products. A sun
zenith angle of 45° is considered in FondsDeSol to calculate the normalized reflectance.
uncertainty variance-covariance matrix for the 7 spectral bands associated to the normalized
surface reflectance.
Over ocean:
monthly chlorophyll concentration derived from SeaWiFS-OrbView-2
available at 9km.
monthly wind speed derived from SeaWinds-QuikSCAT available at 0.25°.
For both datasets, the ADAM ocean climatology consists in monthly averaged values estimated over the
period 1999-2009. Gaps over small lakes and for
coastline pixels have been filled and described in the products quality flag.
ADAM Database
Database format
The file formats of the ADAM database are NetCDF4/ HDF5.
Given the range of variation for the variables:
REF_LAND: [0; 1];
WIND_SPEED: [0; 35.1] m/s;
CHLORO_CONC: [0; 94.14] mg/m3.
and their expected accuracy (defined by the difference between the maximum and the minimum value of their range
of variation, divided by the number of bits used
for coding), these variables are stored as short integers (1 byte).
The variance-covariance data provided in 12 separate files are stored in float (32 bytes).
Additionally, the ADAM products file contains the geographical coordinates (longitude, latitude) of each grid
cell. They are stored as float (2 bytes).
Reflectance data
The data ref_land are packed and coded in short integer. The unpacking of reflectance data has to
be performed using the following formula: ref= (ref_packed) * scale_factor
with scale_factor = 0.0001 Missing data in the packed array are attributed the value -8421.
The ref_land variable is of dimension [12,7,1800,3600].
Chlorophyll concentration data
The data chloro_conc are packed and coded in short integer. The unpacking of chlorophyll
concentration data has to be performed using the following formula: scale_factor = 0.00143645815072645 add_offset = 47.0684242248535 chloro_conc = chloro_conc * scale_factor + add_offset Missing data in the packed array are attributed the value -32768.
The chloro_conc variable is of dimension [12,1800,3600].
Wind speed data
The data wind_speed are packed and coded in short integer. The unpacking of wind speed data has to
be performed using the following formula: ws = (ws_packed) * scale_factor + add_offset
with scale_factor = 5.296775899e-4 and add_offset = 17.75595. Missing data in the packed array are attributed the value -32768.
The wind_speed variable is of dimension [12,1800,3600].

ADAM Toolkit
The theoretical principles stand-alone ADAM calculation tools that allow the computation of the Earth surface
reflectances over the 300-4000 nm spectral range in any observation geometry for the discriminating processing
of the land, ocean, and snow, surfaces, are described in an Algorithm Theoretical Basis Document (ATBD)
available.
The use of the toolkit is further described in the Using
the API section.
Product Quality Information
Quality flags
The quality flag associated to the gridded input data contains information on whether pixels have been
gap-filled or not.
The quality flag is coded in short integer where:
0 indicates no gap-filling
1 indicates gap-filling for chloro_conc data only
2 indicates gap-filling for wind_speed data only
3 indicates gap-filling for chloro_conc and wind_speed data
4 indicates coastline pixels considered as land (i.e. reflectance values in the 7 MODIS bands are
provided) for which the contribution of water may not be negligible
5 indicates snow pixels over polar regions that have been gap filled
6 indicates land pixels (snow) which reflectance values has been clipped to 1.1
7 indicates gap-filling for ref_land data over sea ice (i.e. corresponding to pixels
identified as sea ice in the CryoClim products).
The map of the quality flag for January is illustrated below:
ADAM product quality assumptions and limitations
It must be well understood that the ADAM Tools does not attempt to generate exact value for any given day and
time, but only realistic values of the Earth's surface reflectances (and associated errors for the land
surfaces). Indeed, the use of monthly climatologies (using some gap filling procedures) precludes the
possibility to correctly account for finer temporal variations of the surface state. Accordingly, the
gap-filling performed over sea ice does not allow representing the real spatio-temporal variability of sea ice
optical properties. The climatology of normalized surface reflectance over land is representative of
2005.
Ocean spectral reflectance
Because the wind speed is highly variable in time, the modelling of the glint reflectance can only provide a
realistic value. There is no attempt to generate an exact value for a given day and time. This must be well
understood when using the ADAM tool over the ocean.
The foam reflectance is assumed isotropic in the absence of relevant knowledge. As for the glint, the foam
reflectance is very much a function of wind speed, which is a very variable parameter while ADAM uses a monthly
climatology. Therefore, the foam parameterization is only designed to provide a realistic value, but certainly
not an accurate value for a given place and time.
Uncertainty estimation for soil/vegetation pixels
Let σs be the uncertainty associated to the spectral extrapolation procedure and
σd the uncertainty associated to the directional model. The total uncertainty
σt on the simulated spectro-directional reflectance is the square root of the sum
of σs2 and σd2
Note that the spectral uncertainty accounts for the spectral modelling error and for the spatio-temporal
variability of the surface reflectance within 0.1° resolution and within the time period considered for
aggregation (one month).
BRDF modelling
Soil and vegetation
As revealed by an analysis of LIDAR observations from CALIPSO at 532 nm over land, the reflectance increase
simulated by the BRDF model in the backscatter direction is overestimated over barren surfaces and
underestimated over forests.
Snow mixed pixels
ADAM-V3 climatology over snow has a tendency to provide high reflectance values in the blue-green bands,
exceeding 1.1 which could be overestimated with respect to "reality". The application of the spectral
extrapolation (the spectral shape being constrained by a radiative transfer model) tends to smooth out this
feature.
The modelling of the spectral BRDF for mixed pixels composed of snow and non-snow elements (vegetation and soil)
is complex and has received little attention so far. The scattering properties of snow and vegetation/soil
surfaces are very different: for soil/vegetation, the BRDF is strongly anisotropic with maximum reflectance
observed in the retro-solar direction, while it is more isotropic for snow. To our knowledge, no simple model
exists in the literature that can be implemented in the ADAM processing tools for treating any combination of
snow/vegetation/soil elements.
Therefore, we have considered two cases for modelling the BRDF of snow pixels:
For pixels exhibiting high reflectance values in the visible, close to those of "pure" snow, we have
considered that the non-snow elements can be neglected. Therefore the ART snow model is applied as
described in TN4.
Otherwise, the surface behaves like a Lambertian surface with constant reflectance values independent of
the viewing direction.
Observation geometries
There is no control that the observation geometry (either the default one proposed in the web interface,
or the one chosen by the user) may correspond to a possible observation configuration for the
pixel/period considered. In particular, there is no relation between the possible range of values of the
sun zenith angle with latitude and time. The user must thus make sure to request a combination of
observation conditions that are physically sound.
In ADAM API Tools, the range of variation for the view zenith angle is set to [-65°; and 65°]. Beyond,
the BRDF models that are used are not validated and are likely to provide unphysical reflectance
values.
The range of variation for the relative azimuth angle is [0°; 360°]. The backward scattering direction
corresponds to 0° while the forward scattering direction corresponds to 180°. The perpendicular plane of
observation is defined for a relative azimuth angle of 90° or 270° (the BRDF models being symmetrical
with respect to the principal plane).
The user has however the possibility to change this variation interval by modifying the standard ADAM
configuration file, but this will be done on his own responsibility.
For the same reason, the maximum value of the illumination zenith angle is limited to 70°. However, the
user may control the behaviour of ADAM outputs when going beyond this threshold value:
either all the reflectance outputs associated to out of range illumination directions are set to
0;
or all the reflectance outputs associated to out of range illumination directions are set to
NaN;
or all the reflectance outputs associated to out of range illumination directions are set to the
reflectance value that corresponds to the threshold sun zenith angle.
Using the Website
The website you are currently viewing is the primary interface to the ADAM Surface Reflectance Products. The
intended workflow of the website is for the user to:
navigate to a region of interest;
visualise the reflectance for wavebands of interest; and optionally:
perform a download or calculation using customised parameters.
The website is presented in three sections: Map, Map Controls, and Calculation / Download. These sections are
illustrated in the screenshot below, and further described in the Help sections:
The map is an interactive tool presenting the monthly climatology of ADAM surface reflectance data,
pre-calculated in the standard viewing geometry (sun zenith angle at 45°, viewing at nadir), in the 7 MODIS
wavebands as well as in a preselected set of five broad spectral domains.
Map Display Mode
The map can be presented in one of two possible modes:
Colour Composite: where the red, blue and green channels of the map image are derived from the wavebands
defined using the corresponding drop-down menu. Choices for the source of each channel include the seven
individual MODIS band wavebands or the reflectance averaged over predefined broad spectral domains.
Commonly used settings are:
'True Colour'; Red: MODIS 1 (645nm), Green: MODIS 4 (555 nm), Blue: MODIS 3 (469nm)
(Traditional) 'False colour'; Red: MODIS 2 (858 nm), Green: MODIS 1 (645nm), Blue: MODIS 4 (555nm)
Spectral Domain Averaged: where the map is rendered according to a scale for the average across a
spectral domain. The scale is depicted using the well-known 'jet' colour scheme ranging from blue to red for low
to high reflectance respectively. The scale itself can be visualised by expanding the legend in the top right of
the map.
Regardless of the colour display method, the map is presented according to the Plate Carrée (geographical
coordinates) projection. When the map is zoomed to a very local scale the individual pixels of the underlying
database are clearly visible, enabling for calculations to be performed with relative precision.
Coastlines and country boundaries can be added to the map by enabling the 'Coastline and Countries'
tickbox.
Download Map
A map image can be saved locally by using the 'Download Map' button. The map can be downloaded in either
PNG or GeoTiff format. The GeoTiff image is georeferenced, allowing it to be imported into a GIS (Geographical
Information System) and overlayed with other layers. Depending on the browser being used, clicking on the
'Download Map' button will either prompt the user to save the resulting image, or simply present it in a
new window. In the case of the latter, the image can be saved locally by right-clicking on the image and
choosing 'Save Image..' or similar.
Navigating the Map
Navigating the map is performed by selecting the 'Pan and Zoom' tool in the toolbar above the map:
and dragging the map using the mouse. Zooming can
be achieved
either using the mouse-wheel, the zoom buttons in the top left of the map, or by holding down the shift key on
the keyboard whilst dragging a rectangle to quickly specify a precise zone.
Selecting Pixels for a Calculation
Beyond simply presenting the data in the ADAM database, the map also serves as a method for defining a
geographic zone to perform a custom calculation. Defining a zone is performed by enabling the selection tool in
the toolbar above the map: . Once the select
tool is
activated, dragging on the map will result in pixels being highlighted. To navigate the map after making a
selection, the user must click again on the pan tool to
re-enable navigation mode.
Note that the number of pixels that can be selected for calculation operations is limited to 5 x 5
degrees. If the user selects more than the maximum limit an error is displayed and the zone diminished
to the maximum allowable area.
The coordinates of the selected zone are presented in the 'Region of Interest' section in the Calculation
/ Download section, as discussed in the following section in the Help Documentation. The user is able to
manually type coordinates into the top/left/bottom/right boxes to define exact coordinates should they already
have the coordinates of their zone of interest.
Using the Website: Performing a Calculation
As stated earlier, the ADAM website provides a user-friendly interface to the underlying calculation code.
Beyond the visualisation of data via the map, the website allows the user to perform four discrete operations:
Spectrum graph: reflectance spectrum over the spectral domain and in the observation geometry (only 1
viewing direction) selected by the user
BRDF graph: sampling of the Bidirectional Reflectance Distribution Function for a single spectral domain
specified by the user (narrow or broad band), either in 2D for a transect along particular plane of
observation (principal plane being the default), or in 3D.
Time series graph: reflectance value for each month, in a narrow or broad band and in the observation
geometry (only 1 viewing direction) selected by the user
The uncertainty on the reflectance calculation is available ONLY for land pixels.
The results for Land, Snow, and Ocean, pixels are presented in separated graphs, except for Time Series graphs
where the distinction is made only for Land and Ocean surfaces.
If 6 or fewer pixels are selected in the region of interest, the reflectance values are plotted for each
individual pixel, resulting in graphs said to be created in 'pixel mode'. If more than 6 pixels are selected,
statistics (minimum, maximum and average reflectance, as well as standard deviation) and they are therefore
presented in 'statistical mode'.
In 'pixel mode', there is a separate graph presented for each land and snow pixel (in order to
ease the interpretation of the reflectance values and associated uncertainty), whereas ocean pixels (for which
no uncertainty is available) are plotted on the same axes.
After a given calculation, the data resulting from the calculation is available for download in NetCDF format
from the 'Download Data' tab, together with the corresponding original ADAM data.
Spectrum Graph
The Spectrum Graph operation results in a graph of the reflectance spectra over the 240-4000 nm domain, for the
defined month and observation and illumination geometry.
To obtain a spectrum graph, ensure that there are pixels selected on the map using the select tool: , choose 'Graph: Spectrum' from the 'Operation'
menu, complete
the neccessary parameters and click 'Submit Request'
As is the case for the BRDF graphs, if 6 or fewer pixels are selected in total, a line is plotted for each
pixel, resulting in graphs said to be created in 'pixel mode'. If more than 6 pixels are selected, statistics
are generated of the minimum, maximum and average reflectance for each of the three surface types: land, ocean
and snow, and they are therefore presented in 'statistical mode'.
In 'pixel mode', there is a separate graph presented for each pixel, whereas ocean and snow pixels are plotted
on the same axes.
As with all the graphing functions, the data resulting from the calculation is available for download in NetCDF
format from the 'Download Data' tab.
An example of a 'statistical mode' spectrum graph is given below.
BRDF Graph
The BRDF Graph works similar to the Spectrum Graph. After selecting a zone on the map and choosing 'Graph:
BRDF', the parameters suitable for the BRDF graph are presented.
Note that for the BRDF display, the View Zenith Angle is sampled between [-65°;6°] with a ° angular step, except
+-1° around the hot spot direction where the angular sampling is enhanced with a 1° step.
BRDF Graphs can be generated either in 2D (for a particular Plane of observation) or in 3D (polar plot).
As with all the graphing functions, the data resulting from the calculation is available
for download in NetCDF format from the 'Download Data' tab.
An example of a 'statistical mode' BRDF graph is given below.
Time Series Graph
The Time Series Graph presents the same information as the normal BRDF graph, but for a
single View Zenith Angle (VZA) and over 12 months.
As with all the graphing functions, the data resulting from the calculation is available
for download in NetCDF format from the 'Download Data' tab.
An example of a 'pixel mode' Time Series graph is given below.
Using the Website: Data Download
In addition to performing calculations and graphs, the user is able to download untreated
data directly from the source ADAM database using the Data Download operation.
The data downloaded corresponds to the month and region selected on the map, and there
is a button for convenience to select the entire globe.
Note that the entire database is several gigabytes in size and the extraction and
preparationa of a large extraction will take some time, please be patient.
Alternatively to selecting a particular month or region, the entire raw ADAM Database
for all months, including support files, can be downloaded
from here.
The entire, raw ADAM Database can also be downloaded in Sinusoidal projection from here.
The Digital Elevation Model including elevation, slope, aspect and hill-shading can be downloaded from here. It is presented in the same resolution as the ADAM data.
The GlobAlbedo Validation Dataset can be downloaded from
here.
Using the Website: Command Line Usage
Normal interaction with the ADAM Website involves a human operator using the graphical user interface with a
mouse and keyboard, entering values into the parameters inputs and clicking submit as required. Advanced users
have requested that certain features of the website be available via command line, making it possible to write
scripts to perform 'batch operations' without the need to perform time-consuming manual repetitive
tasks.
This approach should not be confused with the API discussed in the following sections of the Help Documentation.
Using the website via the command line allows the user to perform exactly what is available via the website
normally, nothing more. Its sole advantage is that it offers a method for executing repetitive tasks that would
otherwise be performed by performing many calculation/download clicks in the website user interface. The
calculations are always physically performed on the webserver, and there are no further parameters or
functionality beyond those available via the web site when accessed in the normal way. Command line usage of the
website can be thought of as the equivalent to having a team of workers each using the website in the regular
way under your direction, allowing high repeatability but with no extra functionality.
Using the website via the command line requires an understanding of the syntax that the website itself uses to
communicate with the ADAM server. When the user interacts with the website via the command line they are
effectively building the same requests as the website itself, in this way the ADAM server makes no distinction
between the two.
The best method for explaining the syntax is by example, the following text is an example request for performing
a download of ADAM data, and is exactly the same as the request issued by the website when used via the normal
graphical user interface.
Note that this example provides the URL to which the request is submitted
(http://adam.noveltis.fr/wsgi-apps/web_run_calc.py), and then the various parameters for performing the
'Download' operation type.
The above request can be submitted from your web browser (for example click on it !), or copy and pasted into a
command line used by wget or curl like this: (scroll to the right to see the full line)
For the above wget command the response will be written to the file out.json. The response is a
computer-readable response in JSON format
indicating the location of the resultant data, and the URLs of any graphs that may have been generated. It is
the responsibility of the user to interpret the response and use it as neccessary, presumably launching
subsequent wget / curl requests to download the operation results.
There are libraries available for parsing (=interpreting) the JSON output for all languages, these are
listed at the bottom of the JSON home page.
The following is a second example, this time for a Spectrum Graph request:
The recommended method for performing command line requests is by taking a working request and cutomising it to
suit the requirements. Working requests can be obtained by performing an operation on the website in the normal
way (i.e. via the graphical user interface) and inspecting the Debug Log. In the debug log there is a line
labelled: "received request dictionary:" which lists the various parameters and their values that were submitted
following that request. The dictionary provides a list of parameters and values which can then be modified as
required for incorporation into a command line request.
A screenshot is given below indicating the request parameters given in the Debug Log. These key/value pairs are
identical to those given in the examples above.
The following section, Using the API will discuss the
ability for an advanced user to download the actual code behind the ADAM website onto their own computer,
allowing them to truely customise and extend the ADAM toolkit for maximum flexibility.
Note the technique of initially performing an operation in the website in order to obtain the request dictionary
in the debug log is also applicable when using the API, because the API uses the same dictionary syntax as the
website to define new ADAM jobs.
Using the API (Application Programming Interface)
The calculations performed by the ADAM website are implemented using a purpose-built library written in the
Python programming language. In IT parlance such a library is usually referred to as an API (Application
Programming Interface). The API is in contrast to a GUI (Graphical User Interface), where the user interacts via
graphical widgets such as buttons, menus and lists, and also in contrast to a Command Line Interface where all
functionality is acheived via an operating system shell prompt.
The API allows a user to perform and interpret calculations entirely within the programming environment. This
greatly enhances the efficiency of complex operations by oblivating the need for the exporting / importing of
intermediate data stages and by allowing the user to benefit from the range of external libraries available in
the programming language for visualisation, processing and so on.
It is possible for users to download the API and use it locally on their own computer hardware. This allows for
the extension of ADAM calculation code to meet specific requirements, as well as the ability to launch
computationally intensive operations against powerful local hardware.
Due to its complexity, the API has its own documentation site specialised for users with a programming
background. The API documentation includes instructions on how to download and install the API, descriptions of
its various components, and example scripts illustrating how it can be used.
This film demonstrates the use of the ADAM website. It needs to be redone with a voiceover.
