Paper Abstract

Transmission spectra recorded using a Fourier Transform Spectrometer at the Atmospheric Radiation Measurements (ARM) Southern Great Plains (SGP) site are analyzed in order to derive atmospheric temperature profiles. The analysis is carried out using the Sequential Evaluation Algorithm for Simultaneous and Concurrent Retrieval of Atmospheric Parameter Estimates (SEASCRAPE) code, which uses a priori information to arrive at a statistically meaningful retrieval. Two different a priori profiles are used, the first is the SEASCRAPE retrieved temperature and water vapor profiles derived from ARM SGP emission spectra recorded near in time to the transmission spectra, the second is a sonde average temperature profile with a reasonable local water profile also used for the initial emission retrievals. We find that the best results are arrived at by using the emission retrieval as the a priori profiles as the initial starting point. Using the sonde a priori results in temperature and water vapor profiles that do not replicate the spectrum well.
