Getvar Returned Large SLP Values Occasionally

[zhanshi1997]

Hello, I am wondering if anyone had the same problem or could help me with this. Really appreciate any help.

So I have wrf output files and try to get the sea level pressure by:
slp_sim = getvar(wrfout, 'slp')
The returned results are around 1040 to 1050 hPa while slp from ERA5 reanalysis is around 1016 hPa.
Also, this happens only in a few output files (one time step output per file). For example, when I use an output file of different time, it matches with the reanalysis.

Attached are two wrf output files. I got large values in Aug 16_00 file, while Aug 16_03 is good: https://drive.google.com/drive/folders/1o2JtpElNSTTM68dDx_3QxijfEx9afc27?usp=sharing
