中文摘要: 基于地基毫米波云雷达与FY-4A卫星对云顶同步观测的特点，分析云雷达垂直顶空观测云顶高度与FY-4A卫星AGRI载荷通道数据之间关系，提出了地基云雷达与FY-4A卫星云顶高度联合反演方法，实现云雷达安装点周边区域卫星云顶高度的融合反演，并对反演结果进行验证分析。结果表明，AGRI载荷的第11~14通道值与云雷达观测云顶高度呈线性相关，且卫星通道值与云雷达观测云顶高度比值呈现冬季最小，春秋次之，夏季最大的季节性变化特点；星地融合反演云顶高度与云雷达观测云顶高度相关系数0.84，融合后比融合前均方根误差减小0.7km，提高了卫星云顶高度的反演精度。
Abstract:Based on the characteristics of simultaneous observation of cloud tops by ground-based millimeter-wave cloud radar and FY-4A satellite, the relationship between cloud top height observed by cloud radar and AGRI load channel data of FY-4A satellite was analyzed, and a joint inversion of cloud top height based on cloud radar and FY-4A Satellite is proposed. The cloud top height of the satellite in a certain area around the installation point of the cloud radar is retrieved, and the inversion results are verified and analyzed. The results show that the 11-14 channel DN value of FY-4A satellite is linearly correlated with the cloud top height of cloud radar. Moreover, the ratio of FY-4A satellite channel value to cloud top height observed by cloud radar shows the seasonal characteristics of minimum in winter, followed by spring and autumn, and maximum in summer. The correlation coefficient between cloud top height obtained from satellite-ground fusion inversion and cloud top height measured by cloud radar is 0.84, and the root-mean-square error decreases by 0.7km after fusion, which improves the inversion accuracy of satellite cloud top height.
