MARS

Specifies the requested levels.

levelist=<value>

Valid values have to correspond to the selected levtype. For example, model levels can range from 1 to 137. Pressure levels are specified in hPa, e.g. 1000 or 500. Potential vorticity levels are specified in units of 10-9 m2 s-1 K kg-1. For ocean fields, values are specified in metres below sea level, e.g. 5.  > Operational model level definitions

Examples:

levtype=ml,                                                 # all operational (HRES) model levels (e.g.Cycle 49r1, with 137 model levels)
levelist=1/to/137                                   

levtype=ml,                                                 # model level 1, at the top, also used for 
levelist=1                                                     # single level fields, e.g. logarithm of surface pressure


levtype=pl,                                                   # fields on the lowest 5 pressure levels (in hPa) 
levelist=1000/950/925/900/850                  # of the operational (HRES) model levels (e.g. Cycle 49r1)

Note that levelist=all is not permitted.
