| 摘 要： | 介绍了从FY3A卫星IRAS仪器的通道辐射率估算OLR的技术,包括:用红外辐射传输正演的方法建立IRAS多通道辐射率加权求和计算OLR的反演模式,以及由此模式计算得到的OLR产品。模式的全球RMS=3.53 W/m2,表明远高于从NOAA AVHRR通道5亮温计算OLR的反演模式精度。文中给出IRAS全球OLR产品个例,及该OLR产品与NOAA-17 OLR产品的精度对比。

| Abstract: | In this paper,the author presents a technique for estimating OLR from FY3A IRAS multichannel radiance observations.It includes the development of an OLR inverse model by infrared radiative transfer calculation and regression analysis,and the incorporation of the model into the IRAS OLR processing software.The RMS of the model for global 3812 soundings is 3.53 W/m2,which shows a much higher quality of IRAS model than that of NOAA AVHRR.The author gives an example of FY3A IRAS global OLR product,and carefully... |
