Hello everyone,

I am using the FNL dataset, replacing the land cover data for D03, updating SST, and generating the met file. When running real.exe, I encountered the following error:

d02 2015-01-06_06:00:00 Input data is acceptable to use:
metgrid input_wrf.F first_date_input = 2015-01-06_06:00:00
metgrid input_wrf.F first_date_nml = 2015-01-05_00:00:00
At line 777 of file module_date_time.f90
Fortran runtime error: Bad value during integer read

After thorough checks, I found that there is an issue with my d02 met data for 2015-01-06_06:00:00. When I open LU_INDEX, all LUCC classifications are 0. I don't know why this is happening; essentially, it occurs at least once every day. Can someone please help me?

Attached are my files for your reference. Thank you all!

Due to continuous testing where I changed the time, some inconsistencies in time might exist.

I would like to apologize for the long delay in response. Between holidays, unplanned time out of the office, the AMS conference, and planning for our WRF tutorial taking place this week, we got pretty behind on forum questions. Thank you so much for your patience.

Are you still experiencing issues with this?
Thank you for your reply. It's definitely been a while, so I don't quite remember how I solved this problem. In the meantime, I recompiled WPS and WRF, and retested MPI. The back runs fine. Thanks
Also, if I just run metgrid.exe serially, it doesn't error. In addition, ulimit -s unlimited may be useful at runtime.
