Re: help needed using mixed resolutions meteo files

Dear alicec, thank you very much for your prompt answer which is turning out to be correct. I am presently testing your suggestion and it seems that I won't need neither to specify the number of unique grids since the program is able to use the finest available grid. This was a feature I already exp...
