OCO-2 Ancillary Absorption Coefficient Tables V5.2The ACOS/OCO-2/OCO-3 ABSCO tables are “lookup tables” that supply cross section values for absorbing gases in the Level 2 algorithm (L2) retrieval process. They record molecular absorption cross-sections over the range of relevant wavelengths, temperatures, and pressures in units of cm^2 /mol for the gases O2, H2O, and CO2. During the L2 generation process the retrieval algorithm computes atmosphe
