Abstract

Abstract

In this paper, SST data of AMSR2, GMI, WindSat and HY-2A RM in 2016 are used to analyze the space-time coverage and the accuracy of remote sensing SST in the Arctic. The results show that, the space borne microwave radiometer SST retrievals coverage rate and effective coverage days in winter are lower than that in summer, and the effective SST coverage rate of GMI is lower, and AMSR2 is higher. When AMSR2, GMI, WindSat and HY-2A RM space borne microwave radiometer SST data are combined used, the SST coverage rate can be between 12%-15% in February, and the number of effective observation days is better than 26 days. The SST coverage rate is higher than 26% in the whole August, and the number of effective observation days is better than 29 days. The error of the space borne microwave radiometer SST data in the Arctic is larger than that of the global average. The accuracy of AMSR2 data is the best one, the accuracy of WindSat data is close to that of AMSR2. The RMSE of GMI SST is about 2 times larger than AMSR2, and the accuracy of HY-2A RM data is lower than that of any other space borne microwave radiometer.
