温度与气压反演结果的分析

Analysis of retrieval results of temperature and pressure

介绍低轨卫星计划的发展情况及温度和气压的反演过程,讨论和分析CHAMP掩星数据采用不同上边界高度反演的温度值。结果表明:上边界高度值越大,反演的温度阔线精度越高;上边界高度值越小,模型误差对温度和气压反演精度影响越大。

The development status of low-orbit satellite projects and the retrieval procedure of temperature and pressure are introduced.The retrieval temperature values of CHAMP occultation data in different upper boundary height are discussed and analyzed.The results show that the bigger the upper boundary height is,the higher the retrieval accuracy of temperature; the smaller the upper boundary height is,the bigger the influence of model errors on the retrieval accuracy of temperature and pressure is.
