Hi all,
I am currently having an issue with the met_em* files generated by metgrid.exe
I am interpolating the SST (from ERA5) to my domain but I am seeing some interpolation artifacts that I can't explain.
I played with the options in METGRID.TBL.
First try was:

Second try:
Left panel is the source data used: ERA5 grib file. Plots are SST in K color range: 300-305K

can you please advise me on what may be wrong here?
Cheers
