Dielectric Properties, Density and Wetness of Surface Snow for SAR- Ground Truth
Listed in NASA Earthdata CMR
Ground truth data for SAR- images was collected in western Dronning Maud Land during austral summer 2003/2004.
Description
Data set includes measurements of dielectric properties, density and wetness of the surface snow from 50 cm deep snow pits and observations of snow pack stratigraphy and surface roughness. Dataset covers a 350 km long traverse form the edge of an ice shelf to a mountain range ~ 300 km from the coast.
Snow pits were excavated every 5 km along the transect.
