SST融合产品在渤黄海的质量评估与修正研究
Quality assessment and correction of SST fusion product in the Bohai Sea and the Huanghai Seas
摘要
Abstract
Sea surface temperature (SST) is a key parameter used in physical ocean research and has an important influence on sea-air interaction and global climate change. Space-borne microwave and infrared radiometers are the main methods used in SST remote sensing. However, although microwave radiometers provide all-weather tech-nology their spatial resolution is sparse, and although infrared radiometers have a good resolution they are affected by cloud. In this study, a 0.1° daily SST fusion product is analyzed using the optimum interpolation method. Data resources include WindSat, AMSR-E, ASMR2, HY-2 RM, MODIS, and AVHRR. Buoy data are used to validate and correct the fusion SST product and its SST characteristics in the Bohai and the Huanghai Seas are also studied. Re-sults show that the RMS error of this SST product is 1.1℃, but this decreases slightly after correction. SST characteristics show the lowest standard deviation of SST is in winter, and SST tends to be inhomogeneous in spring when sea temperatures rise.关键词
