Revision as of 08:54, 11 February 2025
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/
Contents
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 (see Table), using the functional formula for the shape and band intensity (as a function of temperature). Temperature dependency is extended from 100 to 800K.
N2-N2
The N2-N2 continuum file combines all data (roto-translational, fundamental and first overtone bands) from Karman+2019: https://hitran.org/cia/ (N2-N2_2021.cia file).
O2-O2
The O2-O2 continuum file combines all data from Karman+2019: https://hitran.org/cia/ (O2-O2_2018b.cia and O2-O2_theory_temp_2018.cia files).
CH4-CH4
The CH4-CH4 continuum file combines all data from Karman+2019: https://hitran.org/cia/ (CH4-CH4_2011.cia file). Only a single CH4 CIA band has been characterized so far (see Borysow & Frommhold 1987).
H2O-H2O
The H2O-H2O continuum is taken and interpolated from the MT_CKD continuum v_4.0.1 (https://github.com/AER-RC/MT_CKD_H2O)
H2-H2
The H2-H2 continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.
CO2-H2
The CO2-H2 continuum file combines all data from Turbet+20, Mondelain+21 and Fakhardji+21 ; it extrapolates -- whenever possible -- the temperature dependency.
CO2-CH4
The CO2-H2 continuum file is built from Turbet+20 and extrapolates -- whenever possible -- the temperature dependency.
CO2-O2
The CO2-O2 continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.
O2-N2
The O2-N2 continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.
H2O-AIR (H2O-O2 / H2O-N2)
The H2O-AIR continuum is taken and interpolated from the MT_CKD continuum v_4.0.1 (https://github.com/AER-RC/MT_CKD_H2O)
H2O-CO2
The H2O-CO2 continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.
CH4-N2
The CH4-N2 continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.
H2-N2
The H2-N2 continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.
H2-He
The H2-He continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.
H2-CH4
The H2-CH4 continuum file combines all data from Karman+2019: https://hitran.org/cia/ and extrapolates -- whenever possible -- the temperature dependency and the wavelength range.
