EAM is running on an unstructured finite element grid, with both spectral element data (“GLL data”: vertex data given on the GLL nodes) and “PG2 data”, finite volume physgrid” data, given as cell averages for each cell. See CAM-SE Grid Overview todo: add a picture of the PG2 grid to the grid overview page. Atmosphere Grid Overview (EAM & CAM)
Here we compare several options for plotting this data:
