Abstract

Atmospheric spectra are recorded at a number of sites around the world as part of the program of the Network for Detection of Stratospheric Change (NDSC). In many cases, it is possible to derive significant information on the height profiles of the gases whose line spectra are observed. In this paper I will examine the altitude information available in two classes of measurement in routine use by the NDSC, namely microwave thermal emission and infrared solar absorption. I will outline closely related algorithms in operational use for the microwave measurements and under development for the infrared, and show selected results for both cases.
