Two methods for performing clear-air temperature retrievals from simulated radiances for the Atmospheric Infrared Sounder are investigated. Neural networks are compared with a well-known linear method in which regression is performed after a change of bases. With large channel sets, both methods can rapidly perform clear-air retrievals over a variety of(More)

We present a new technique for the fast computation of near-monochromatic atmospheric trans-mittances in the infrared, utilizing compressed look-up tables, that is well suited for nadir viewing satellite and airplane observations. The algorithm is very simple to use in radiative transfer codes and is easily adapted to provide analytic Jacobians of(More)
