Abstract : A field and laboratory measurements program sponsored by the Office of Naval Research, Cambridge Research Laboratory and Cold Regions Research and Engineering Laboratory is being conducted to determine the response of microwave radiometers to various snow conditions. The field portion of the program was carried out within the confines of Crater Lake National Park, with data obtained from new fallen powder snow and old metamorphosed snow. The measurements were made at three frequencies, 13.5 GHz, 37 GHz, and 94 GHz, with microwave temperatures recorded for both horizontal and vertical polarizations at viewing angles ranging from nadir to the local horizon. Similar laboratory measurements were made of artificial snow manufactured in an environmental chamber in which snow temperature and moisture content can be controlled. (Modified author abstract)
