Validation of FY-3E/MERSI-LL Sea Surface Temperature

Presented at the GHRSST XXIII international science team meeting, 27 June-1 July 2022, online and in-person (Barcelona). #GHRSST23

Short abstract

The FengYun-3E(FY-3E) satellite is the first early-morning orbit satellite in China’s polar orbiting meteorological satellite family. It was launched from the Jiuquan Satellite Launch Center of China on July 5, 2021. Its local time at descending node is 5:30 AM. The split window data of Medium Resolution Spectral Imager-Low Light(MERSI-LL) onboard FY-3E is used to estimate SST. Bias and RMSE of FY3E/MERSI-LL SST from January to February 2022 are -0.02 and 0.47 by comparison with in situ buoy data(iQUAM). Further validation against in situ and CMC will be discussed during the GHRSST23 meeting.
