Continuum Database

As of February 2025, we have now implemented a new continuum database in the Generic PCM. The continuum files are available here: https://web.lmd.jussieu.fr/~lmdz/planets/LMDZ.GENERIC/datagcm/continuum_data/

CO2-CO2

The CO2-CO2 continuum file combines:

• the COA CIA band at 0-250cm-1 (Gruszka and Borysow, 1997), extrapolated down to 100K.
• All CIA and dimer bands listed in Tran et al. 2024, using the generic temperature dependency between 100 and 800K.

N2-N2

The N2-N2 continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.

O2-O2
