CASPR
Known Problems

General Problems

• Interpolation of clear sky values to cloudy areas: The interpolation of clear sky temperatures and albedos to cloudy areas, required for the calculation of cloudy sky parameters, is sometimes problematic. This is particularly true for single image processing (as opposed to the time series approach). Cloudy sky results in coastal areas and areas of extensive cloud cover have large uncertainties! It's not a problem with the code; it's just a difficult problem.

Platform-Specific Problems

• Sun Solaris: IDL v5.4 differs from IDL v5.3 in that it defaults 64 bit rather than 32 bit mode. This can result in errors in using the shared object C routines. This may be a problem specific to Sun Solaris on certain computer architectures. Current work-arounds: (1) start IDL with "idl -32" rather than "idl"; (2) use the "-xarch=v9" option during the linking and compiling stage for Sun Solaris.
• Microsoft Windows: Somebody needs to figure out how to compile the C functions into DLLs. At present, CASPR will only run under Unix (including Linux).
