-The SeaWiFS Data Analysis (SeaDAS) is a comprehensive image analysis package for the processing, display, analysis, and quality control of ocean color data.

Coart Coupled Ocean and Atmosphere Radiative Transfer

This is a tool for you to calculate radiance and irradiance (flux) at any levels in the
atmosphere and ocean (0.2100um).
Specify the inputs simply by clicking the buttons and
changing the default numbers in the table. Setting Ocean_depth=0 reduces it to conventional
atmospheric radiative transfer model.



libRadtran - library for radiative transfer - is a collection of C and Fortran functions and programs for calculation of solar and thermal radiation in the Earth`s atmosphere. libRadtran is freely available under the GNU General Public License.


The International Ocean-Color Coordinating Group

-The main objectives of the IOCCG are to develop consensus and synthesis at the world scale in the subject area of satellite ocean color.


The AERONET (AErosol RObotic NETwork) program is a federation of groundbased
remote sensing aerosol networks established by NASA and LOAPHOTONS
(CNRS) and
is greatly expanded by collaborators from national agencies, institutes, universities,
individual scientists, and partners. The program provides a longterm,
continuous and readily
accessible public domain database of aerosol optical, mircrophysical and radiative properties
for aerosol research and characterization, validation of satellite retrievals, and synergism
with other databases. The network imposes standardization of instruments, calibration,
processing and distribution.

Msphinx (6S)

Satellite Process Handling Images uNder XWindow

The strong points of Sphinx reside in its:

integration of the laboratory's multidisciplinary expertise inspacebased
climate research.
construction under UNIX and the X11 Window System to render it machine independent.
visualization of images that is the nearest possible to the original data without superfluous menus
or overlays.
efficient internal data structure that is quickly adaptable to various common image formats.
multispectral visualization of satellite sensor data.
printing of processed images.

HydroLight (not free)

The HYDROLIGHT radiative transfer numerical model computes radiance distributions and
related quantities (irradiances, reflectances, diffuse attenuation functions, etc.) in the ocean.
Users can specify the water absorption and scattering properties, the sky conditions, and the
bottom boundary conditions in various ways: by selection of builtin
defaults, by reading in
data (such as WETLabs® ac9
data), or by writing their own Fortran subroutines
to define their input. HYDROLIGHT then computes the inwater
light field and other quantities
of interest to optical oceanographers, such as the waterleaving
radiance and remotesensing
reflectance. Output is presented as ASCII printout, as Excel® spreadsheets, or as digital files
designed for plotting and analysis using IDL®.


The GlobColour project is demonstrating an EO based service supporting global ocean carbon cycle research. Through this web portal, the project provides scientists with a long time series of
consistently calibrated global ocean color information.
