Description Calls vanilla database and gets required fields to remove CO2 and water vapor contributions to the radiance spectra. This only works on 143 point TES spectra. This function depends on 2 external programs: vanilla and correlated-k code (see co2_new for more information). Usage is restricted to linux.
Arguments and Return Values Arguments: Vanilla select fields, vanilla database directory. Return Value: TES measured radiance with radiative contributions due to CO2 and H2O vapor removed. Optionally, the original input values from the vanilla call can be returned as well in a structure.
Usage Syntax: atrem("vanilla select fields","vanilla data directory", [str = 1]) "vanilla select fields": String containing conditions that restrict the input data "vanilla data directory": Path where vanilla DATASET file is contained struct: return a structure with individual vanilla input components as well as corrected radiance - 0 (default) returns radiance only, 1 returns individual components atrem only works on 143 point single scan TES data (Use "scan_len 1 1" in select string)
