摘要
用GMS5分裂窗通道和水汽通道的资料,以及船舶浮标站实测的海温资料进行反演海温和格点分析的试验研究。比较了三种不同的海温反演方法,其中用分裂窗通道资料并考虑削弱路径的方法,与用分裂窗通道资料并考虑水汽亮温的方法精度较好(平均绝对误差分别为0.93 °C和0.95 °C)。文中还用递归滤波分析方法较好地解决了质量控制和客观分析的问题,分析出的格点场与实测海温分布基本一致。
The tests had been carried out by using GMS5 split window channels data and water vapor channel data, as well as ship and buoy observation data for SST retrieval and its objective analysis. Comparing three different SST retrieval methods, the method of using split window channels data and concerning weaken track ,and the method of using split window channels data and concerning water vapor channel data got higher precision. The quality control and objective analysis by using recursive filter method had good result, and tests showed that the analysis grid field was in good agreement with real observations.
