Remote Sensing Techniques, Temperature 

 Sensing, Optical Scintillations 



The NOAA Wave Propagation Laboratory, at 

 the inception of NOAA, was oriented toward re- 

 search on the effects of the environment on the 

 propagation of electromagnetic waves. Through 

 the past 10 years, the orientation has been re- 

 versed in order to undertake research concerning 

 the use of the effects on acoustic and electromag- 

 netic waves to probe the atmosphere and the 

 oceans, i.e., remote sensing (Ref. I). The devel- 

 opment of the acoustic sounder (Ref. 2), pulse 

 Doppler weather radars, the FM-CW Doppler 

 radar and the Doppler lidar have been notable 

 accomplishments (Ref. 3). The emphasis is now 

 shifting from instrument development toward the 

 use of these remote sensing instruments and their 

 unique capabilities for research toward a better 

 understanding of the geophysical environment. 



Mathematicians in NOAA's Wave Propagation 

 Laboratory have had a continuing interest in the 

 mathematical techniques for the retrieval of at- 

 mospheric temperature profiles from observations 

 of the infrared emission of the atmosphere at sev- 

 eral wave lengths emitted from different atmos- 

 pheric depths. The techniques have had applica- 

 tion to the remote sensing of atmospheric temper- 

 ature profiles from satellites (Refs. 4, 5. 6). 



The Optical Propagation Group at NOAA's 

 Wave Propagation Laboratory, originally interest- 

 ed in the effect of a turbulent atmosphere on the 

 propagation of light, has applied this knowledge 

 to remote sensing of atmospheric winds and tur- 

 bulence and, most recently, rainfall rate and rain- 

 drop site distribution by means of optical beams 

 as viewed in the forward propagation direction. 

 As well as the experimental work, the group has 

 made major progress in developing and extending 

 the theory of scintillations in a turbulent medium, 

 including the explanation of the saturation effect 

 of optical scintillations (Refs. 7-12).
