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 name of resource file is c2l_CFIO_offline.rc
An example resource file to go from c90 to 180x91 is given below, note you must give the time you want to regrid.
<verbatim>
- required entries
IM_World: 90
JM_World: 540
LM_World: 72
nlon: 180
nlat: 91
input_file: myinputfile.nc4
output_file myoutputfile.nc4
year: 2000
month: 12
day: 1
hour: 21
minute: 0
- optional entries, the defaults are in parentheses
NX: 1 (1)
NY: 6 (6)
USE_SHMEM: .false. (.false.)
CONSERVATIVE: .true. (.false.)
vars: (give a comma separated list of variables you want regridded) </verbatim>
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):
