Re: regridding CMIP5 GCM output

There are several tools including NCL you can use to regrid GCM outputs.

1. use CDO tools - there are several command prompt operators available.
You will have to do a little bit of research.

       A CDO command line example is given below,

              cdo remapbil,*1x1grid_target.txt* input_filename.nc
output_filename.nc ## remapbil stands for bi-linear interpolation

       The target grid details given in *1x1grid_target.txt* have the
following details (regrid to 1x1 lat/lon),

gridtype = lonlat

xsize = 360

ysize = 180

xfirst = 0.5

xinc = 1.0

yfirst = -89.5

yinc = 1.0

You should also read the ncl-talk discussion on this. Dennis raised some
important points on regridding.

2. NCL has several methods. I am sure if you search the ncl-talk archinves
you will find several examples. Have a look at the recent version released
yesterday - http://www.ncl.ucar.edu/Applications/ESMF.shtml
