摘要

Dual polarization brightness temperature retrievals from the small Airborne MIRAS (AMIRAS) are provided. Single snapshots at instrument polarization frame and also at horizontal and vertical polarization are shown. Maps of first Stokes parameter using concatenated snapshots are presented for land areas (including geo-location), sea water and fresh water. Finally, brightness temperature of single points on ground as a function of incidence angle are given. They show relatively high dispersion due to the limited performance of the instrument, especially its low resolution and low snapshot rate.
