SnowEx17 Laser Snow Microstructure Specific Surface Area Data V001
Listed in NASA Earthdata CMR
This data set reports vertical profiles of snow reflectance, specific surface area (SSA), and optical equivalent diameter (grain size) at Grand Mesa, Colorado, USA, a snow-covered, forested study site about 40 miles east of the city of Grand Junction, CO.
Description
Reflectance was measured <em>in situ</em> using a 1310 nm integrating sphere laser device and converted to SSA and optical equivalent diameter.
