Hemispherical-directional reflectance factor (HDRF) of snow surfaces retrieved from airborne camera measurements in Antarctica during austral summer in 2013/14 ...

The hemispherical-directional reflectance factor (HDRF) of snow surfaces was measured in Antarctica during austral summer in 2013/14. The HDRF was retrieved from airborne measurements using a digital 180° fish-eye camera onboard the research aircraft Polar 6 operated by the Alfred Wegener Institute,...
