Abstract:

基于红外辐射传输方程,模拟了代表全球各种天气状况3812条大气廓线的大气顶射出长波辐射通量密度(OLR),以及FY-3BVIRR通道5辐射率,通过统计回归分析,建立了通道5亮温与通量等效亮度温度的统计回归关系式.将回归模式应用于FY-3BVIRR仪器的L1级数据,处理出了卫星观测时刻的OLR格点场产品,产品的精度经由与观测时间相近的NOAA-18卫星同类产品对比得出,对于全球日平均产品,两者的系统均方根误差RMSE=10~13W/m2,相关系数R=0.97~0.98,误差的主要原因是对同一地理位置两星的观测时间不尽相同.文中给出了处理出的OLR产品实例,以及产品的应用范围和初步应用个例
