Abstract Extraterrestrial Solar Spectral Irradiance (ESSI) is an important parameter for calculating Band Mean Solar Irradiances (BMSI) of different satellites. In order to probe into the problem as to which ESSI dataset could acquire a more accurate BMSI result, the authors selected 4 ESSI datasets, namely SBDART simulated solar spectrum dataset, oldkur.dat dataset from MODTRAN4.0, Thuillier solar spectrum dataset and WRC solar spectrum dataset, to calculate BMSI for HJ-1A CCD1(B1-B4), CBERS-02 CCD(B1-B5), Landsat5 TM(B1-B4) and ASTER (B1-B8).A comparison was made between the calculated BMSI result and the BMSI result published by satellite operators.It is found that the calculated BMSI results using WRC solar spectrum dataset and SBDART dataset have a smaller error in comparison with published BMSI, followed by oldkur.dat, while the calculated BMSI results using Thuillier solar spectrum dataset have larger errors than other datasets.
