Py4CAtS --- Python scripts for Computational ATmospheric Spectroscopy


Molecular Spectroscopic Databases

In order to compute line-by-line cross sections and optical depths, you first have to extract the relevant spectroscopc line parameters from the HITRAN or GEISA databases. See CO.vSEan for a typical line parameter file (listing the "essential" parameters only, i.e., line positions v, Strengths, lower state Energy, air broadening widths and its temperature dependency exponent n). According to the default naming convention, the filename head indicates the molecule, and the extension indicates the data columns.

Atmospheric Data

The file containing an user's atmospheric profile data has to be in xy format:
(netcdf will come soon (hopefully))
