L-band satellite simulator alike SMOS and SMAP

Code for a satellite simulator alike SMOS or SMAP by using the CMEM as radiative transfer, CLM as input for land surface model and taking into account the orbit geometries and radiometer features.

For the case of SMOS, multi-incidence angle product is produced.
The simulator requires as input some satellites characteristics like orbit inclination, footprints latitudes and longitudes, radiometer antenna diameter, operation frequency.

The operator is thought to be integrated in any Fortran90 code that might require synthetic observations of brightness temperature in horizontal and vertical polarization.

Code was written within the research project FOR2131 of the German Research Foundation (Deutsche Forschungsgemeinschaft DFG).
