Analytical Study of Passive Techniques for Measuring Atmospheric Parameters.

Abstract

Calculations are presented that show the degree of recovery of both atmospheric water-vapor and temperature distributions using passive infrared and microwave radiometry-assuming ground-based radiometers. A gradient technique is used to recover a temperature profile with 2 inversions and a water-vapor profile with 5 inversions. The method is applicable to distributions to 2 Km. Calculations are also presented that show the affect of water-vapor and temperature on radio wave propagation and the affect of visibility on the passive methods. (Author)
