APPLICATION OF STATISTICAL ESTIMATION TECHNIQUES TO GROUND-BASED PASSIVE PROBING OF THE TROPOSPHERIC TEMPERATURE STRUCTURE

The theory of radiative transfer in the microwave region is discussed. A method for the numerical solution of a Fredholm integral equation of the first kind is derived and illustrated. A least-squares analysis of microwave absorption data to determine line width for water vapor and oxygen is presented. Calculations of the error covariance matrix and quality-criterion values to be expected when the probing for the tropospheric temperature structure from microwave emission measurements are presented.
