ARTS Absorption Lookup Table for a Wide Range of Atmospheric Conditions

General description This dataset provides an absorption lookup table for the Atmospheric Radiative Transfer Simulator (ARTS). The data is stored in the ARTS XML data format. The dataset consists of the following files: abs_lookup.xml Meta data describing the lookup table in ASCII format abs_lookup.xml.bin The grids and absorption cross section in binary format The lookup table covers wavenumbers from 10 to 3,250 cm-1. It is valid for surface temperatures between 200 to 400 Kelvin and water vapor mixing ratios from 4e-5 up to 0.4. The spectral coverage in combination with the wide range of validity make the lookup table suitable to calculate radiative fluxes even in extreme climates. The dataset includes absorption cross-sections for the following species: CH4 CO CO2 H2O N2 N2O O2 O3 Usage with the radiative-convective equilibrium model konrad The lookup table can be used by the ARTS radiation class provided by the radiative-convective equilibrium (RCE) model konrad. This allows the user to perform RCE simulations with line-by-line longwave radiation. The environment variable ``KONRAD_LOOKUP_TABLE`` is used to tell the model where the lookup table is located: export KONRAD_LOOKUP_TABLE="path/to/abs_lookup.xml" References ARTS: radiativetransfer.org konrad: github.com/atmtools/konrad
