卫星遥感海表温度反演研究

针对东海渔区的海洋渔业应用 ,以中国东海渔区 ( 118°～ 130°E ,北纬 2 4°～ 36°N)为例 ,使用美国NOAA气象卫星AVHRR数据的红外波段 ,从NOAA 14的 1B数据预处理出发 ,开展了卫星遥感海表温度 (SST)反演模型研究及其业务化运行的卫星遥感渔业信息分析软件开发等工作。使用所开发软件对气象卫星数据进行处理 ,得到海表温度图像或海温等值线图等信息 ,为海洋渔业提供必要的基础资料

Study on Sea Surface Temperature Retrieval from NOAA/AVHRR Data

To the needs of ocean fishery of East China Sea Fishery Area, the stud y was carried out using satellite NOAA/AVHRR data. The study area is about 124 °～ 130°E, 24°～36°N. The satellite sea surface temperature (SST) retrieval model of th e study area was established by regression of match data extracted from NOAA/AVH RR 4, 5 channel data and in situ data measured by ship. Then the model was reali zed by software developed with Visual Basic 5.0, Visual C++ 5.0 and other tools. A series of NOAA/AVHRR data was processed using the software. SST images and SS T contours of the study were got, which can be used as an important information to reduce the fish-finding time of fishery and thus reduce the cost of fishery industry. They are also important materials for other ocean studies.
