Estimation of ATMS Antenna Emission From Cold Space Observations
TL;DR: It is found that the antenna emission is significant and dominates the scan-angle-dependent features in the ATMS antenna temperatures and the impact of antenna emissivity to calibration accuracy of antenna temperature products is significant.
