atm_field

Workspace.atm_field: AtmField

An atmospheric field in ARTS, this is the main atmospheric data structure in ARTS.

The atmospheric field defines the altitude of the top-of-the-atmosphere, as well as the variables that are required for the radiative transfer calculations along a path through the atmosphere. The field can be accessed at any altitude, latitude, longitude path that is within the atmosphere to access the relevant atmospheric point data (atm_point).

Note that constraints on the various field parameters may be imposed by extrapolation limitations on the field parameter itself, causing some or large swaths of the atmosphere to be inaccessible.

The atmospheric field may, but does not have to, consist of the following:

  • Temperature - Atmospheric temperatures in Kelvin

  • Pressure - Atmospheric pressure in Pascal

  • Wind - Atmospheric wind field in meters per second

  • Magnetic Field - Magnetic field in Tesla

  • Species content - Usually the volume-mixing ratio of various species, with some exceptions. See SpeciesEnum for more details.

  • Isotopologue ratios - The isotopologue ratios of various species. See SpeciesIsotope for more details.

  • Non-local thermodynamics ratios - Unitless [pure-style] OR Kelvin [vibrational-style] ratios replacing the Boltzman distribution used in the LTE calculations.

  • Scattering species content - See user guide for more information. This is custom data to aid scattering calculations.

For more information, see The atmosphere.
