As a BEAM plugin, the Snow Radiance Processor needs the following software to be installed in advance:

The BEAM software can be obtained from the BEAM download page (www.brockmann-consult.de/beam). Note that the Snow Radiance Processor software has been developed in the frame of BEAM 4.8. Full compatibility with older BEAM versions cannot be guaranteed, therefore, it is strongly recommended to use the Snow Radiance Processor with BEAM, version 4.8. Once newer releases of BEAM are published, the Snow Radiance software will be updated accordingly if required.

The Snow Radiance software delivery consists of several jar files: a core module, the modules of the BEAM MERIS/AATSR Synergy Toolbox and for AATSR recalibration, and adjusted BRR (Bottom of Rayleigh Reflectance) and SDR (Surface Directional Reflectance) modules, which provide additional Java classes used by the toolbox:

These files need to be downloaded from the BEAM plugin page:

or the Snow Radiance Wiki page:

The files need to be copied into the 'modules' folder of the BEAM installation. Note that existing versions of these jar files need to be replaced/overwritten. There should not be more than one jar file for each of these modules in the 'modules' folder!
