Abstract

An optimization program for least-squares estimation of nonlinear parameters is applied to the problem of atmospheric temperature sounding. From simulated sets of intensity measurements at 12 frequencies in the 15μ CO2 atmospheric band, this program is used to solve for the temperatures at 5 altitudes throughout the troposphere. Both temperature and altitude can be treated as variables in order to obtain the best match to the real profile.
