Click for answer. Where can I find gridded meteorological data to simulate the Chernobyl accident?
• Click for answer. I have FNL meteorological files, which I use to compute trajectories with HYSPLIT. I need to extract the numerical value of some fields (geopotential at 700 hPa at each i,j grid point). I ran your program example which extracts the first field (precipitation), but I do not know how modify the program to extract geopotential at 700 hPa.
