Background material on theoretical and practical aspects of the use of millimeter wave radiometric equipment for remote probing is presented. Specifications for development of the Mark I Radiometric THERMASONDE(TM) are listed and performance characteristics are described. The paper, 'Use of Millimeter Wave Radiometry to Remotely Measure Atmospheric Stability,' presented at the Symposium on Advances in Instrumentation for Air Pollution Control, which describes work accomplished under this contract is given as Appendix I of this report. Simulated and experimental radiometric results are presented and discussed for climatological and equipment effects in the observing of lapse, ground-based, and elevated inversions. A nonlinear nomogram was developed to correct for radiometric smoothing of intensity and height of ground-based inversions. Different observing modes and signal processing techniques appear to assist in the interpretation of radiometric soundings for use in detecting elevated inversions. (Author)
