本文利用AVHRR资料反演海表面温度,并用台站及船舶观测资料进行订正计算月平均海水表层温度场,结果表明,海水表层温度与AVHRR资料反演的海水表面温度之间基本呈线性关系,比例系数接近1.0,位移订正随季节变化较大;用AVHRR资料计算海水表层温度,可以很好地反映海水表层温度在较大尺度上的分布结构.
In this paper, the AVHRR data are used to inverse the sea surface temperature and the monthly mean sea surface temperature field is corrected by using station and ship observation data. The results show that there is a linear relationship between sea surface temperature and seawater surface temperature retrieved by AVHRR data, The coefficient is close to 1.0, and the displacement correction changes greatly with the seasons. Using AVHRR data to calculate sea surface temperature can well reflect the distribution structure of sea surface temperature on a larger scale.
