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

Abstract

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