[Wrf-users] Using HadGEM2-ES cmip5 output in WRF

[jagan TNAU]

Dear All,

I have cmip5 HadGEM2-ES netcdf file which has z axis as hybrid vertical
height coordinate (meters). I want this to be interpolated to required
pressure level so that I can ingest in to the WRF. The CMOR pre-processor
available at
http://www.meteo.unican.es/wiki/cordexwrf/SoftwareTools/CmorPreprocessordoes
not provide procedure for this kind of files. Is there any procedure
available for using this data in WRF.

Please find below the ncdump output for netcdf file to be interpolated.

Can I get some help on this please.
