atm_fields_compact

property Workspace.atm_fields_compact

A compact set of atmospheric fields on a common set of grids.

Data is supposed to contain basic atmsopheric fields for a RT calculation, i.e., temperature, altitude, and gas VMRs. It can furthermore contain fields describing scattering species like mass content, mass flux, number density of diverse scattering species.

VMR fields are unitless, scattering species fields are supposed to be in SI units (i.e. kg/m3 for mass contents, kg/m2/s for mass flux, 1/m3 for number densities).

The data are stored in a GriddedField4.

The first field in the matrix (i.e., first matrix column) has to be atmospheric pressure. Apart from this, the order of the fields is free. Field content (apart from pressure) is identified by their given field name tag. Furthermore, absorption species (e.g. VMR) fields and scattering species fields are related to abs_species and scat_species entries, respectively, by their field name tags. The tags must exhibit the following structure:

0. species identifier: Fields, supposed to be sorted into vmr_field, must be headed the tag ‘abs_species’. Names of scattering species fields likewise must be headed by the ‘scat_species’ tag. Temperature and altitude fields do not hold any heading tag.

1. species name: The (core) name of the field: ‘T’ for temperature, ‘z’ for altitude, the absorption species name (e.g. ‘H2O, ‘O3’, etc.) for absorption species, the scattering species name (e.g. ‘IWC’) for scattering species. For scattering species, this part is matched against the scattering species name part of the scat_species tags.

2. field type: This has to be given for scattering species only, indicating the type of the scattering species fields, i.e. ‘mass_density’, ‘mass_flux’, ‘number_density’, ‘mean_mass’.

Dashes (‘-’) serve as delimiter, separating the elements of each field name tag.

Usage: Used inside batch calculations, to hold successive atmospheric states from an ArrayOfGriddedField4.
