Py4CAtS --- Python scripts for Computational ATmospheric Spectroscopy
- HITRAN molecular database
- GEISA data bank
- JPL - Submillimeter, Millimeter, and Microwave Spectral Line Catalog
The file containing an user's atmospheric profile data has to be in xy format:
(netcdf will come soon (hopefully))
- comment lines in this file have to begin with # in the first column
(Actually 'any' character can be used, i.e. using the -c option the default # can be changed)
- a comment line starting with #where: can be used to include some info for the job
- at least 2 comment lines are mandatory:
#what: followed by identifiers, e.g. altitude, molecular names, pressure, or temperature
#units: followed by the physical units, e.g. km, mb, K, ppm
-
If the very first column is altitude, some abbreviated forms are recognized, too:, e.g.
# altitude pressure temperature
or
# z p T
and
# km mb K
- a column for altitudes is mandatory (marked ALTITUDE or HEIGHT in the #what: record)
- columns with profiles not requested by the user (e.g. IR inactive gases) are ignored
- the number of columns in the data section and the number of identifiers and units given above have to be identical
- Example:
#comment this line will be ignored
#info: this is ignored, too
#note: the next line is optional
#where: bavarian foehn
#what: Height Temperature CO2 H2O NO
#units: km K cm-3 cm-3 cm-3
