In-orbit calibration scanning microwave radiometer on HY-2 satellite of China

摘要

In this paper, we give a method of calibrating T on HY-2 satellite by cross comparing them with those from WindSat satellite. The results show that the re-calibrated T were obviously closer to the simulated T by using ECWMF data. We will further investigate the accuracies with newly launched microwave radiometer AMSR2.
