deviations of Arctic open water, first-year and multiyear sea ice. Data
from 6.9 to 89 GHz based on AMSR-E/2 observations with incidence angle
55°, at 1.4 GHz on SMOS observations averaged over 50° to 55° incidence
angle, collected for footprints with pure surface types in the Round
Robin data package of the ESA Climate Change Initiative project on sea
ice. Solid lines denote vertically polarized Tbs, and H horizontally. Note that lines connecting the Tbs are meant
for easy reading, but not for interpolation between the observation
frequencies.
