<div dir="ltr">Dear All,<br><br>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 <a href="http://www.meteo.unican.es/wiki/cordexwrf/SoftwareTools/CmorPreprocessor" target="_blank">http://www.meteo.unican.es/wiki/cordexwrf/SoftwareTools/CmorPreprocessor</a> does not provide procedure for this kind of files. Is there any procedure available for using this data in WRF.<br>
<br>Please find below the ncdump
output for netcdf file to be interpolated.<br>
<br>Can I get some help on this please.<br><br><div dir="ltr">--------------------------------------------------<br>netcdf va_6hrLev_HadGEM2-ES_rcp45_r1i1p1_200512010600-200603010000 {<br>
