2.Data format :
For a given molecular species, each file describe absorption cross-section data corresponding to :
- a given temperature in K,
- a given pressure in Pa (which could be unknown),
- a given resolution in cm-1 or nm (which could be unknown),
- some references.
In the spectral range WnMin – NnMax (cm-1).
A compressed cross-section file is named “xxxx_rrrr_[yyyy]_tttt_pppp.asc.gz” where :
- xxxx represent the name of the molecule,
- rrrr the resolution,
- yyyy the reference(s),
- tttt the temperature,
- pppp the pressure.
Example of a file name : cfc-14_00.01_[19]_216.00_005012.93.asc.gz
