SnowEx20 Laser Snow Microstructure Specific Surface Area Data V001
Listed in NASA Earthdata CMR
This data set contains vertical profiles of snow reflectance, specific surface area (SSA), and spherical equivalent snow grain diameter.
Description
Data were collected during the SnowEx 2020 Grand Mesa, Colorado Intensive Observation Period between 27 January and 12 February 2020. Reflectance was measured at snow pits using one of two integrating sphere laser devices, IRIS (InfraRed IntegraXng Sphere) or IceCube.
SSA and spherical equivalent diameter were then derived from reflectance.
