CalVal Software Tools

Tool Description
BEAM BEAM is the Basic ERS & Envisat (A)ATSR and Meris Toolbox and is a collection of executable tools
and an application programming interface (API) which have been developed to facilitate the utilisation,
viewing and processing of ESA MERIS, (A)ATSR and ASAR data.
6s Radiative Transfer Code.

the satellite signal in the solar spectrum 6S\: An overview
IEEE Trans. Geosci. Remote Sensing, vol. 35, no. 3, pp. 675--686, 1997.
TELIMAGO ALOS Expert tool by GAEL Consultant (Linux).
MODTRAN MODerate spectral resolution atmospheric TRANSsmittance algorithm and computer model (developed by U.S. Air Force Research Lab).
Streamer Streamer - a radiative transfer model for computing either radiances (intensities) or irradiances (fluxes).
Esov NG Esov NG - a desktop application to calculate and visualize orbit tracks and sensor swaths.
Recalibration of AATSR Reflectances This tool allows for the recalibration of AATSR reflectances. It was implemented as BEAM 4.5 operator within the MERIS/(A)ATSR Synergy project, based on algorithms by courtesy of D. Smith et al. (RAL). - To run this tool, you will need the latest BEAM software, which can be downloaded above.
LIBRADTRAN Library for radiative transfer - a collection of C and Fortran functions and programs for calculation of solar and thermal radiation in the Earth's atmosphere.
