Kyo,

Can you test Alex' modifications using your domain/case? I currently don't have 
a domain to test his modifications. BTW, have we loaded NCEP reanalysis into 
RCMED? I don't see it in the parameter table.

Thanks.

> I found some critical bugs while using Jinwon's version 2.1 with CMIP5 
> outputs and NCEP DOE reanalysis 2 data.
> They are common problems of 0.1-incubating (RC4) and Jinwon's 2.1
> Currently RCMES cannot properly handle NCEP/NCAR reanalysis or CMIP5 outputs
> 1. longitude issue
> When reading longitude from netcdf files, the modules in files.py 
> automatically convert longitudes larger than 180 to negative values. This 
> becomes a problem because in GCMs, the longitude array is not monotonically 
> increasing any more (0, 2.5, ...., 180, -175, -172.5, -170,.......... -2.5) 
> due to the conversion. If we choose North America region, RCMES subsets data 
> over the Tibetan Plateau for regridding.
> 2. latitude issue
> In NCEP/NCAR reanalysis, latitude variable (lat) monotonically decreases from 
> north to south. With the current version, users must re-order data so that 
> latitude values increase monotonically from south to north.
> 3. leap years
> Some CMIP5 GCMs do not consider leap years at all. Our current time decoding 
> reading modules cannot handle these model outputs.
