Abstract

 The objectives of this study are to validate SST (Sea Surface Temperature) of GCOM-C SGLI (commonly known as "Shikisai") in Tokyo Bay and to investigate the characteristics of monthly average SST. SGLI-derived SST was compared 210 samples with in-situ SST at three station in Tokyo bay from January 2019 to August 2019 at 11:00 AM synchronized with satellite within 30 minutes. As a result, the accuracy of SGLI SST in the bay was calculated with a standard deviation of 0.90 °C and a bias of - 0.27 °C when cloud removal was performed using the quality flag. The SST data derived from SGLI had an acquisition rate of 9 to 33% each month. Furthermore, as a feature of the monthly mean SST distribution, SGLI data well captures the front, especially at the bay mouth in January and February.
