1/17/2016 1/19/2016 11:46 AM 3 0.05 M M I estimate 0.05" H2O, with maximum snow depth of 0.5". Much of snow originally caught was lost due to evaporation during wind. My estimate is based on melt of residual catch (ice) of <0.02", and timely monitoring of catch at site 4 mi east of here.
1/22/2016 1/27/2016 10:45 AM 6 M 8.2 2.32 Unable to access site until 1/27/16 (remained at home 1/22 for beginning of storm; GSFC closed to nonessential personnel 1/23 through 1/26). Wind and deep snow resulted in drifting and underfilling of snow catch. Above freezing temperatures 1/25 to 1/27 resulted in considerable compaction and melting of snow on ground.
