boudary conditions WRF-LES| help me pls


New member
hi everyone, i'm new using WRF-LES and i want to run my first simulation. I found the neccesary files to run my simutation but i'd like to know what boundary conditions should i use?. When i was using WRF-ARW i used to put GFS/FNL/ERA5 but i prefer to read a recomendation.
Each one has their own advantages. ERA has 1 hour time steps (so does FNL I think) GFS is widely available and has 3 hour time steps. I would look and see what the research papers normally use and go with that.
