| 摘 要： | 在下垫面相对比较复杂的四川区域,为了解风云二号F(FY-2F)卫星相对湿度产品的可靠性,利用2013~2017年加密观测期间研究区内11个加密观测站点探空探测资料与FY-2F卫星湿度产品进行对比分析,给出了FY-2F卫星相对湿度产品的分析结果,并从偏差统计、相关系数统计等方面对比分析了二者数据间的差异。结果显示:FY-2F卫星湿度产品整体数值小于探空湿度,和探空数据间的相关系数区间为-0.16~0.64;相对偏差区间为-1.65~-0.19;相关系数变化趋势均随气压层高度变化呈线性变化趋势;FY-2F卫星产品的可靠性随着高度升高而升高。

| Abstract: | In order to understand the reliability of the humidity data derived from FY-2F satellite over the Sichuan province,FY-2F humidity data was compared with the Sounding data of eleven observation stations in Sichuan during the period 2013-2017.The correlation coefficient and the relative error between these two kinds of data were discussed,so as to analyze the applicability of the FY-2F data in Sichuan.The average correlation coefficient is range from-0.16 to 0.64,and the average relative error is range from-0.19 to-1.65.The variation of average correlation coefficient have linear trend in 300hPa,400hPa,500hPa and 700hPa.And results analysis indicates that the reliability of the FY-2F humidity data increases with the air pressure height. |
