Dear Collegues,

I am running the WRF model with the high resolution ECMWF Operational Model forcing data. The upper-air relative humidity (157 | 100 | * | | RH | % | Relative Humidity ) is missing in my dataset at some levels. Can I replace the relative humidity by the upper-air specific humidity (133 Q, mass of water vapour / mass of moist air)?

Arthur,
You need to replace all levels of RH by SPFH. WPS cannot handle RH in some levels and SPFH in other levels.
 
Thanks for your help! Can I kindly ask you to provide me the relevant record (row) for SPFH which I should add in my Vtable.ECMWF.txt file?

Best regards,
Artur
