Subject Re: obs4MIPs program

Chris,

I checked in "obs4MIPs"  in SVN.  You have the whole thing with examples 
for TRMM and ECMWF including the resource files (.rc). Taking care of 
Python dependencies will be the most difficult part I think, but the 
it's pretty straightforward to run.   Can someone try to run the 
examples on your side to know what needs to be improved?

You can use XLS spreadsheet to match variables(ex:ECMWF<->CMIP5) or use 
the python list directly in the resource file(ex:TRMM<->CMIP5), but the 
second option is less user friendly to maintain/read.

You can also create User Defined Functions that can be imported 
on-the-fly and create a new data array using the variable in the input 
file.  For example, with ECMWF data we want to convert "specific 
humidity (Q)" to "relative humidity(RH)" using "dew point (d2m)".

I am currently creating a resource file to convert MERRA data to CMIP5, 
I will give you an example when its completed.  MERRA data is HDF-EOS so 
let see how I can make this work...  :-)


Happy to hear that it's gonna be used!
Denis
