中文摘要: 为充分发挥FY-2C静止卫星在人工影响天气和气候领域的重要作用,基于SBDART辐射传输模 式,利用该卫星通道4(3.5~4.0μm)的探测数据,反演了云粒子有效半径,并与TERRA上M ODIS的相应产品做了比较。结果表明,FY-2C和MODIS资料能一致地反映云粒子有效半径分 布的主要特征,但反演的粒子大小存在差异。反演算法、卫星分辨率及选取通道的不同可 能是造成两种资料间差异的主要原因。
Abstract:To make fully use of FY-2C geostationary satellite in the field of wea ther modification and climate, cloud effective particle radius was retrieved fro m FY 2C Channel 4(3.5~4.0μm)data based on the radiative transfer mode, SBDA RT. While comparing to the corresponding MODIS products on TERRA, it is shown tha t FY-2C presents similar distribution patterns of cloud effective radius to MOD IS, but with some differences in particle size. The different retrieval algorithm s, satellite resolutions and channels may be the main factors causing these diff erences between two data sets.
