The physical basis for sea ice remote sensing
Webb1. Introduction. Trends in sea-ice extent as seen from satellites – rather coarse indicators of the health of the polar ice covers – have been monitored for only three decades (1978-present) (Reference Comiso, Parkinson, Gersten and Stock Comiso and others, 2008).Yet, these satellite estimates have served as the bellwether of climate of the Arctic and, to a … Webb18 mars 2013 · The Bidirectional Reflectance Distribution Function (BRDF) has been calculated for three types of bare sea ice with varying surface roughness ( σ = 0.1–10 cm) and ice thicknesses (50–2000 cm) over… PDF View 2 excerpts, cites background and results Polar Sea Ice Identification and Classification Based on HY-2A/SCAT Data
