CAR LEADEX Arctic Sea Ice and Tundra BRDF Measurements L1 V2 (CAR_LEADEX_BRDF)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/0vr2cw18jixl
CAR LEADEX mission measured bidirectional reflectance functions for four common arctic surfaces: snow covered sea ice, melt season sea ice, snow covered tundra, and tundra shortly after snowmelt.
Description
The measurements show how the reflectance differs amongst the mentioned arctic surfaces and provides insights into the variability of albedo in the arctic. This data set consists of observations made with the CAR instrument and includes values for bidirectional reflectance factor at varying spectral bands.
