New optical and microwave integrated vegetation indices (VIs) were designed based on observations from both field experiments and satellite (HJ-1 and RADARSAT-2) data. It was found that these VIs perform better in estimating the structure parameters of maize, such as Leaf Area Index (LAI), height and biomass, than the original ones. This investigation focused on the difference of interaction between...
Monitoring soil respiration (R s ) at regional scales using images from operational satellites remains a challenge because of the problem in scaling local R s to the regional scales. In this study, we estimated the spatial distribution of R s in the Tibetan alpine grasslands as a product of vegetation index (VI). Three kinds of vegetation indices (VIs), that is, normalized...
