Atmospheric Refraction Phenomena
Principal Investigator: Lehn, W.H.
Licensed Year(s): 1987
Summary: To study the optical refraction and image transmission in the lower layer of the atmosphere, in particular under conditions of temperature inversion. To improve the understanding of these processes, and to continue to search for remote sensing techniques that provide temperature profiles through optical measurements....

Licence #4015
Principal Investigator: Lehn, W.H.
Licensed Year(s): 1984
Summary: To investigate optical refraction in the lower layers of the atmosphere (anomalous refraction, such as the superior mirage and optical ducting). Photographic recording of land forms and their refracted images: measurement of refraction and horizon shift; some measurement of atmospheric temperatures in the lowest layers (10-15 meters); local surveys of the photographed land forms....
