CRREL Returns to Senator Beck Basin for "off Snow" LIDAR Survey
Following a small pilot study in spring 2010 (see April "Satellite overflight of CSAS study area brings gaggle of scientists"), the Army's Cold Regions Research and Engineering Laboratory - aka CRREL - began a new LiDAR (light distance and ranging) research program in Senator Beck Basin in early September, 2010. Researcher Eli Deeb, from the ERDC-CRREL Snow Hydrology group conducted "snow off" surveys of the snow-free terrain surrounding the Senator Beck and Swamp Angel study plots. Eli was assisted by Jeff Deems, from Western Water Assessment and the National Snow and Ice Data Center, and CSAS staff. The CRREL team will return to CSAS' Senator Beck Basin during the winter of 2010/2011 for "snow on" surveys of the same terrain, then comparing those to the "snow off" surveys to generate very high resolution maps of snowcover at those sites, and the spatial variation of that snowcover.
