Hello! I used Era5 data as input.
data1.grib is the pressure level 3D data and data2.grib is the surface layer data. I learnt that I need to link land-sea mask.grib and geopotential.grib. Therefore, I put all the required data in the same file.
1. ln -s ungrib/Variable_Tables/Vtable.ERA-interim.pl Vtable
2. ./link_grib.csh /scratch/yuyp/run_test/era5data/*
3. ./ungrib.exe
Is this process correct?
should I do it separately? For example,
1. ln -s ungrib/Variable_Tables/Vtable.ERA-interim.pl Vtable
2. ./link_grib.csh /scratch/yuyp/run_test/era5data/data1.grib
3../ungrib.exe
4. ln -s ungrib/Variable_Tables/Vtable.ERA-interim.sfc Vtable
5. ./link_grib.csh /scratch/yuyp/run_test/era5data/data2.grib
6../ungrib.exe
How about the Land-sea mask.grib and geopotential.grib? How should I link?
Thank you for your advice and I am looking forward to seeing from you.
Best regards,
Yiping
