Abstract

In order to demonstrate the feasibility of cooperative inversion of the vegetation indexes between FY-3A/VIRR, FY-3A/MERSI and Terra/MODIS, the NDVI from these data was compared. The authors selected 2012 year's data of FY-3A/VIRR, FY-3A/MERSI and Terra/MODIS which is covering the upstream of the Heihe and less cloudiness. The statistical method was used to study correlation of NDVI from the selected data. The result shows that there are significant correlations of NDVI from the data of FY-3A/VIRR, FY-3A/MERSI and Terra/MODIS, and all the correlation coefficients exceeded 0.99.But significant differences are also exist between these data. The causes of NDVI differences were analyzed in detail, and found that spectral response function and radiometric calibration have a certain impact on vegetation index. These ana-lyzes can provide a reference for cooperative inversion of multi-source remote sensing data.
