Description
Metview Macro Library function. Computes the total column integrated mass for the "mdc" (mass density concentration) sum/vertical integral of fields in a FLEXPART output GRIB file.
...
The FLEXPART output GRIB as a fieldset. It takes precedence over source
param
The shortname of the GRIB parameter. If param is "mdc" (mass density concentration) the column integrated mass is computed. Otherwise the fields are simply added up for the specified level range.
top_level
The top height level (inclusive) for the computations. Optional.
bottom_level
The bottom height level (inclusive) for the computations. Optional.
step
The forecast step to extract.
