摘要
地外太阳光谱辐照度(ESSI)是计算给定卫星各波段平均太阳大气外辐照度(MSEI)的重要参数。选取MODTRAN4.0软件中的5个ESSI数据集和Santa Barbara DISORT Atmospheric radiation Transfer (SBDART)工具模拟的ESSI数据集,计算HJ-1A CCD1、CEBERS02 CCD、Landsat TM5(band1~band4)和ASTER(band1~band9)各波段的MSEI。将计算的MSEI与公布的MSEI进行了比较。结果表明,SBDART工具模拟的ESSI数据集和MODTRAN oldkur.dat数据集最适合MSEI的计算,MSEI结果与已发表的MSEI结果一致。使用thkur.dat和newkur.dat数据集计算这些卫星的MSEI存在较大的误差,因此不建议对给定卫星计算MSEI。
Selection of different Extraterrestrial Solar Spectral Irradiance datasets and its effects on Mean Solar Exoatmospheric Irradiance
Extraterrestrial Solar Spectral Irradiance (ESSI) is an important parameter for calculating Mean Solar Exoatmospheric Irradiance (MSEI) of each band for a given satellite. In order to find optimal ESSI dataset for calculation of MSEI, 5 ESSI datasets from MODTRAN4.0 software and ESSI dataset simulated by Santa Barbara DISORT Atmospheric Radiative Transfer (SBDART) tool were selected to compute MSEI of each band for HJ-1A CCD1, CEBERS02 CCD, Landsat TM5(band1~band4) and ASTER(band1~band9). Comparisons between the calculated MSEI and the published MSEI were made. It is found that ESSI dataset simulated by SBDART tool and MODTRAN oldkur.dat dataset are best suitable for calculation of MSEI and the MSEI results are consistent with published MSEI. There are big errors using thkur.dat and newkur.dat datasets to compute MSEI for these satellites, so that they are not recommended to calculate MSEI for given satellites.
