Interpolation of real data initial conditions using ERA5

[ajrosales]

I have next question; I am using the ERA5 dataset to run the MPAS model but as ERA5 has two separated dataset from surface and different levels pressure when I use ungrib.exe to create the intermediate files, I generated them with two prefix (e.g. FNL and SFNL), so if I include two files with different prefix, how can I edit the namelist.init_atmosphere in the &data_sources “config_met_prefix =” to include these two prefix and just one of them?.

You need to concatenate the two files to a sigle file, i.e.,

cat FNL SFNL >> ERA5

Then in your namelist.init_atmosphere, set config_met_prefix = "ERA5"
