Workspace Method AtmFieldsAndParticleBulkPropFieldFromCompact

Description

Extract pressure grid and atmospheric fields from
atm_fields_compact.

An atmospheric scenario includes the following data for each
position (pressure, latitude, longitude) in the atmosphere:
           1. temperature field
           2. the corresponding altitude field
           3. vmr fields for the gaseous species
           4. scattering species fields

This method splits up the data found in atm_fields_compact to
p_grid, lat_grid, lon_grid, vmr_field, particle_bulkprop_field,
and particle_bulkprop_names.
See documentation of atm_fields_compact for a definition of the
data.

Compact states are characterized by having all atmospheric fields
already given on identical grids. That is, no interpolation needs
to be and is performed. Keyword *p_min* allows to remove atmospheric
levels with pressures lower than the given value (default: no
removal). This reduces computational burden and is useful when
upper atmospheric contributions are negligible.

Possible future extensions: Add a keyword parameter to refine the
pressure grid if it is too coarse. Or a version that interpolates
onto given grids, instead of using and returning the original grids.
