摘要: 研究大气水汽的反演及了解其时空变化,对有效评估大气生态服务功能具有重要现实意义。基于石家庄地区CE-318观测的大气水汽数据,结合探空水汽数据和地面水汽压数据,运用传统回归分析、改进型回归分析、分段反演等方法,构建传统回归模型、基于CE-318的大气水汽改进型模型和分季节模型3种大气水汽反演模型,并经过精度对比评估选出适用于研究区的大气水汽最优反演模型。检验结果表明,基于CE-318的大气水汽改进型反演模型的各项精度检验指标均为3个模型中的最佳值,是该地区最优的大气水汽反演模型。

Abstract: It is of important practical significance for effectively assessing the functions of atmospheric ecological services and strengthening the construction of ecological environment to study the inversion of atmospheric water vapor and understand its spatiotemporal change. Based on the CE-318 observed atmospheric vapor data,sounding data and surface vapor pressure data,the traditional regression model,CE-318-based atmospheric water vapor inversion model and seasonal model were constructed by traditional regression analysis and improved regression analysis. The optimal inversion model of atmospheric vapor over the study area was selected by the accuracy evaluation analysis. The main conclusions are as follows: The inversion results of the three models constructed were all relatively satisfactory,and the inversion results of the atmospheric water vapor inversion model based on CE-318 were the most accurate. Its item inspection indexes were the best values in the accuracy tests of the three models,and the atmospheric water vapor inversion models were optimal for the study area.
