The c2l_CFIO_offline.x program is a simple program that uses the I/O layer that MAPL_History uses to read in a file and regrid it to a different resolution using our built in transformations to convert cubed-sphere files to lat-lon files. It also handles both bilinear and conservative regridding. The program is driven through a resource file. It must be run on at least 6 processors via the correct mpirun command for your build.

The c2l_CFIO_offline.x program is a simple program in the fv3 direcotry (GEOSgcs_GridComp/GEOSgcm_GridComp/GEOSagcm_GridComp/GEOSsuperdyn_GridComp/FVdycoreCubed_GridComp) that uses the I/O layer that MAPL_History uses to read in a file and regrid it to a different resolution using our built in transformations to convert cubed-sphere files to lat-lon files. It also handles both bilinear and conservative regridding. The program is driven through a resource file. It must be run on at least 6 processors via the correct mpirun command for your build. It is normally built when you build GEOS-5 and copied to $ESMADIR/Linux/bin

The name of resource file is c2l_CFIO_offline.rc

Line 5:

An example resource file to go from c90 to 180x91 is given below, note you must give the time you want to regrid.

<pre>

# required entries

IM_World: 90

Line 24:

Line 25:

CONSERVATIVE: .true. (.false.)

vars: (give a comma separated list of variables you want regridded)

</pre>

If you choose conservative regridding you must link in the tile file you would need for the 2 resolutions. These can be found here all the .bin files):
