Problem with avg_tsfc.exe

I want to calculate the daily mean surface temperature with avg_tsfc.exe (as described in The WRF Preprocessing System (WPS) — WRF Users Guide documentation). I followed the process described there. I see that everything works smoothly, and I get a message "*** Successful completion of program avg_tsfc.exe ***". But, the TAVGSFC file is not generated. In fact, there is no new file in my folder. What could the problem be? And what would be the solution for that?

Hi,

In your namelist.wps, you specify the following options:

Code: 
&share
start_date = '2020-02-06_00:00:00', '2020-02-06_00:00:00',
end_date   = '2020-02-13_00:00:00', '2020-02-13_00:00:00',
&ungrib
out_format = 'WPS',
prefix = 'FILE',
/
&metgrid
 fg_name = 'FILE',
 io_form_metgrid = 2,
/

Would you please check whether you have "FILE:yyyy-mm-dd_hh" in your WPS directory? if so, how many do you have?

Please issue the command "ls -l FILE:* > log" and send me the log file to take a look.

By the way, what data did you ungrib to produce the intermediate files?
 
Hello!
I think there are 57 files in the directory. However, I have attached the log file as you said.
I am using ERA5 data in this process.

The files look fine. I just did a quick test using FILE from GFS and it works fine for me. I am suspicious whether something is wrong in your intermediate files.

Please issue the command in WPS and send me the log file to take a look:
./util/rd_intermediate.exe FILE:2020-02-07_12 > log

Thanks.
 
I found that there is no surface temperature in your intermediate files. This explains why avg_tsfc.exe cannot yield TAVGSFC files.

This problem can be traced back to the ERA5 data you ungrib. Where did you download the ERA5 data? I attach in this post an instruction how to obtain all ERA5 data files (from CISL RDA) required by WPS. Please take a look.

Hope it is helpful for you.
