Research on the Factors Influencing the Inversion of Cloud Top Properties of Fengyun 4B
摘要
Abstract
The new generation geostationary meteorological satellite FY-4B is equipped with multi-channel scanning imaging Radi-ometer(AGRI).This paper quantitatively calculates the errors caused by the factors of channel brightness temperature,initial estima-tion and uncertainty,uncertainty of forward mode on the retrieval of cloud top temperature,cloud top height and cloud top pressure.The results show that changes in channel brightness temperature have the greatest impact on inversion,changes in initial estimation and its uncertainty have a moderate impact on inversion,and changes in forward mode uncertainty have the smallest impact on inversion.This study can provide important reference basis for improving the algorithm to calculate the property of the FY-4B cloud top.关键词
