What is the regridding value for WAS-22 (0.22 degree)?
Added by Gunavathi S over 2 years ago
Hello all,
I am using WAS-22 data for climate modelling. I need to convert this data from rotated coordinate system to lat /long. I can use this code for conversion "cdo remapbil,r360x180 input.nc output.nc". But I do not know the regridding value for 0.22 degree. Can anyone help me out?

Hi Gunavathi,
without the data file I can only guess.
1. Convert to global 0.22 degrees grid file
cdo -remapbil,global_0.22 infile outfile
2. Extract the region of your regional data
cdo -sellonlatbox,<lonmin>,<lonmax>,<latmin>,<latmax> outfile outfile_regional
or in one step
cdo -sellonlatbox,<lonmin>,<lonmax>,<latmin>,<latmax> -remapbil,global_0.22 infile outfile

Dear sir,
I have attached the metadata details for which I need regridding value? I know the regridding values for 1 degree(360*180), 0.5 degree(720*360) and 0.25 degree(1440*720).What will be the value for 0.22 degree?

Well that's simple:
360 degrees / 0.22 degrees ~ 1636 longitudes 180 degrees / 0.22 degrees ~ 818 latitudes
