本文详细分析了TeraScan系统反演NOAA/AVHRR卫星海表温度的过程,解决了反演过程中的海陆匹配问题和云检测过程中的误检、漏检问题,处理得到2002年(5°~45°N)、(105°~150°E)区域内的卫星海表温度数据。利用东北亚地区海洋观测系统NEAR-GOOS提供的现场海表温度数据做比较,印证NOAA/AVHRR海表温度在西北太平洋海域的精度,并分析其误差产生的来源。 |
In this paper,the processing of NOAA/AVHRR sea surface temperature(SST) by TeraScan system is analyzed.The missed and false cloud pixels are found out to retrieve the SST in the region(5°~45° N,105°~150° E) in 2002.To investigate the accuracy of the NOAA/ AVHRR SST product,NOAA/AVHRR SST are compared with simultaneous NORTH-EAST ASIAN REGIONAL Global Ocean Observing System Regional Delayed Mode Data Base(NEAR-GOOS RDMDB) in-situ data.Finally,the sources of error are analyzed. |
