Matt found problems with handling of input files in CLM when in radians instead of degrees, and also for files on -180-180 versus 0-360. Previously I made sure all input files in CLM where 0-360 and in degree's as there were problems otherwise. There's also quite a few files here to think about. surface datasets, domain files, mapping files (both for model and for mksurdata_map), nitrogen-deposition and aerosol deposition files. I'm not sure if the entire modelling system can handle it if different parts of these files are on different grids or not. I believe all raw datasets for mksurfdata_map are on -180-180. If we create domain files on 0-360 does the mapping still work right? And if we create surface datasets on -180-180, do the aerosol and Nitrogen deposition files still work right?

CLM can certainly check that the input units are degrees and die if not. Or really converting between the two isn't a real issue. I'm NOT sure about the -180-180 conversion though...
