Model levels
The GEOS-5 model layers used for MERRA products are on a terrain-following hybrid sigma-p coordinate. Model-level data are output on the LM=72 layers; the indexing for the GEOS-5 vertical coordinate system in the vertical is top to bottom, i.e., layer 1 is the top layer of the atmosphere, while layer LM is adjacent to the earth’s surface.
