| Abstract: |
| FY-3C MWRI sea surface temperature products are tested according to the lifting orbit, using the International Comprehensive Ocean-Atmosphere Data Set (ICOADS), and the inspected results of different wind speeds and of different solar radiation (day and night) are analyzed. The results show that the absolute error of ascending orbit for FY-3C MWRI SST product is 0.950 K, the root mean square error is 1.278 K, the absolute error of descending track is 1.186 K, the root mean square error is 1.692 K, indicating that the precision of ascending orbit is better than that of descending orbit; The absolute error and root mean square error are analyzed against the wind speed being less than 6 m/s, 6~12 m/s and greater than 12m/s. Results show that the discrepancy between satellite estimated SST and measured SST will increase under the conditions of high wind speed (>12 m/s) and low wind speed (0~6 m/s) in the day time. This research is of great significance for improving the algorithm model and the quality and credibility of products. |
