Information content of remote atmospheric ozone measurements
Abstract
A technique for evaluating the information content of data obtained by remote measurements of atmospheric gaseous components is discussed. The technique is used to analyze the information content of remote sensing in the IR absorption bands of ozone at 9.6 and 8.9 microns. The information structure of measured data relating to the spectral and angular distribution of intrinsic radiation from the earth-atmosphere system as well as to atmospheric transmission at grazing incidence is examined. Information content characteristics are compared for different experimental procedures, and a procedure involving combined nadir and limb measurements is shown to be most advantageous. Recommendations are given concerning the selection of optimum spectral regions for IR measurements of atmospheric ozone.
