Absorption cross section#
Absorption cross section data sets provide the monochromatic absorption cross section spectrum of a given absorbing species at specific pressure and temperature conditions.
Most absorption cross section data used internally by the Eradiate team cannot be distributed easily due to their large size (around 1TB). This, in particular, means that the support for monochromatic simulation is currently limited to selected atmospheric profiles. We plan to improve the delivery of those spectra in the future.
Distributed data sets are managed the data store (see Introduction for details).
Identifiers for absorption cross section data sets
are constructed based on the format

wmaxis the maximum wavenumber value in
Absorption cross section data sets include one data variable:
monochromatic absorption cross section (
one optional data variable:
mixing ratios (
three dimension coordinates:
(temperature may be a non-dimension coordinate) and one optional dimension coordinate:
xs is tabulated with respect to
mr, when present, is tabulated with respect to
mr should be included in data sets where the absorber is a
mixture of different absorbing molecules.
