(Resolved)REAL ERROR: could not find trapping x locations

Hi, I wrote my own intermediate files in binary format with metgrid.exe passed successfully. However I got a "trouble, could not find trapping x locations" after running real.exe.
I tried change the value of 'time_step' but doesn't work. Is there any suggestion? Thanks a lot.

When I debug with code 100, I got detail error messages, here are some of them:

Does it means there is something wrong with my intermediates files?

Thanks,

Huang,
The error message related to attribute like "NetCDF error: NetCDF: Attribute not found" doesn't really matter. However, if the required variables are not found, that implies problem in your met-em file. Below is a few examples:

"NetCDF error in wrf_io.F90, line 2883 Varname XLAT
NetCDF error: NetCDF: Variable not found
NetCDF error in wrf_io.F90, line 2883 Varname XLONG
NetCDF error: NetCDF: Variable not found

Please double check your met_em file.

Yes, there are wrong values in TT variable in the intermediate files. Fixed them and WPS run successfully.

Thanks for Chen's kindly suggestion.
