CDO

Dear All,

I trying to use cdo remapbil,mygrid infile outfile as suggested by [[https://code.mpimet.mpg.de/boards/2/topics/96]]

and mygrid.txt is

gridtype = lonlat
xsize =
ysize =
xfirst =
xinc = 0.44
yfirst =
yinc = 0.44

Here, I could not understand how can I calculate the xsize, xfirst and remaining value for my netcdf having 0.44 resolution.

netcdf /datazone/cordex/data/raw/NAM-44/1hr/WRF/GFDL-ESM2M/hist/pr/pr.hist.GFDL-ESM2M.WRF.1hr.NAM-44.raw.nc {
