I am new to this forum. I am trying to find shape files or feature classes that are relevant to meteorological applications, particularly sea level pressure from the conventional meteorological numerical model runs (GFS, NAM, HRRR, RUC, CFS, etc.). Does anyone have any information on how to obtain this data on a regular basis? Will it require using some intermediate step, like running a GRaDS plotting script or Python to produce a shape file that can be used in ArcMap?
