本文提出一个利用海上实测参数作为外定标值,定量解译气象卫星红外云图中海面温度场的方法。本方法只需要一幅红外云图和两个(或数个)海上实测定标点的同步测值就可以了。用本方法于1982年冬季进行过一次海上试验,取得良好结果,实测数据T_s-D的相关系数优于0.95,解译温度T_(sk)的均方根误差小于1.0℃。
This paper presents a method to quantitatively interpret the sea surface temperature field in the meteorological satellite infrared cloud using the measured parameters at sea as the outer calibration standard. This method requires only an infrared cloud map and two (or several) sea measurement points measured simultaneously measured on it. The method was used to conduct a marine experiment in the winter of 1982, and good results were obtained. The correlation coefficient of the measured data T_s-D was better than 0.95, and the root mean square error of the interpretation temperature T sk was less than 1.0 ℃.
