Hello,
I am trying to drive WRF with EC-Earth output which contains upper air variables(ta,ua,va,spechum) along with a few surface ones (psfc, ps) at 6-hour frequency. Both the soil and surface data is only available at daily resolution (T2,U10,V10,PSML,ST,SM). Per my understanding of WRF, it is okay to only have the UPA forcings at higher frequency since this is being used as lateral boundary conditions as well as the nudging.
This idea seems to be confirmed in this thread Running WRF with CESM2 data (but correct me if this is wrong).
When I follow the steps offered here (split the daily and hourly data, run ungrib twice), I get met_em files that contains a lot of missing values. In all the met_em files on a 6-hour time step, the daily values are missing which makes sense but I thought ungrib might have interpolated them. When I run real.exe I run into the following error once the program reaching such a time step without daily vals:
ERROR in psfc: flag_psfc = 1, flag_soilhgt = 0, flag_slp = 0, sfcp_to_sfcp = T
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 1396
not enough info for a p sfc computation
-----------------------------------------------
Any suggestions to solve this?
Thank you very much,
Jesse
