Sea Surface Temperature (SST) in South China Sea Retrieved from Chinese Satellite FY-3B VIRR Data Chuqun CHEN*, Quanjun HE, Shilin TANG, Haibin YE State key Lab of Tropical Oceanography, South China Sea Institute of Oceanology, Chinese Academy of Sciences *cqchen@scsio.ac.cn Outline • Introduction • Method • SST in SCS • Discussion Introduction In the surface layer of the ocean, Sea Surface Temperature (SST) is the most important parameter, which is widely applied for studying water masses, air-sea interaction, marine ecosystem and environment, and other subjects. The satellite remote sensing technique has become the dominant approach for SST detection. Introduction In decades, a great many satellites with thermal infrared sensors have been launched and huge thermal infrared remote sensing data can be employed for detection of SST. And several Chinese Satellites with thermal sensors are available. FengYun-3 (FY-3) is the second generation polar- orbiting meteorological satellite series of China, and FY-3B is the second satellite of the generation, which was launched in 2010. The visible infrared radiometer (VIRR) is a main instrument aboard the FY-3B. VIRR has 10 bands, and the spectral ranges of the thermal infrared bands 4 and 5 are 10.3~ 11.3μm and 11.5~ 12.5μm, respectively, similar to NOAA/AVHRR. Introduction The South China Sea is a marginal sea that is part of the Pacific Ocean, It covers an area of around 3,500,000 square kilometres,located in 3~23N, 103~ 118E. It is the
