简要概述了多通道海表温度（MCSST）方法中使用的云滤波和大气衰减校正的基本概念。详细描述了MCSST的操作程序和产品。AVHRR为基础的MCSST的比较性能进行了讨论，通过使用JPL卫星派生的海表温度研讨会的结果。对于四个数据期，从MCSST和筛选的船基SST中得出的主要月平均SST异常特征的符号和位置具有令人惊讶的良好对应性。除了在某些地区受到El Chichon火山喷发的火山气溶胶严重影响的一个数据期外，MCSST异常相对于船舶数据的全球统计测量如下：偏差，0.3 - 0.4 ° C（MCSST低于船舶）;标准差，0.5 - 0.6 ° C;交叉相关，+0.3至+0.7。1985年，一种用于NOAA 9数据的改进技术产生了一致的偏差和均方根差，分别接近− 0.1 ° C和0.5 ° C。
A brief outline of the basic concepts of cloud filtering and atmospheric attenuation corrections used in the Multi‐channel Sea Surface Temperature (MCSST) method is given. The operational MCSST procedures and products are described in detail. The comparative performance of AVHRR‐based MCSST'S is discussed via the use of the results of the JPL Satellite‐Derived Sea Surface Temperature workshops. For the four data periods there is surprisingly good correspondence in the sign and location of the major monthly mean SST anomaly features derived from MCSST's and those from a screened set of ship‐based SST's. With the partial exception of the one data period severely affected in some areas by volcanic aerosol from El Chichon eruptions, global statistical measures of the MCSST anomalies relative to the the ship data are as follows: biases, 0.3–0.4°C (MCSST lower than ship); standard deviations, 0.5–0.6°C; and cross‐correlations, +0.3 to +0.7. A refined technique in use with NOAA 9 data in 1985 has yielded consistent biases and rms differences near −0.1°C and 0.5°C, respectively.
