Applicability of Green-Red Vegetation Index for Remote Sensing of Vegetation Phenology
2010
Remote Sensing
Preserved Fulltext
We evaluated the use of the Green-Red Vegetation Index (GRVI) as a phenological indicator based on multiyear stand-level observations of spectral reflectance and phenology at several representative ecosystems ...
We found that GRVI has the following advantages as a phenological indicator: (1) "GRVI = 0" can be a site-independent single threshold for detection of the early phase of leaf green-up and the middle phase ...
The data of leaf area index of FHK site was provided by Tetsuo Okano (Shinshu University, Japan). ...
