GIEWS Earth observation – global indicators


The vegetation indicators (NDVI anomaly, VCI and VHI) provide alternative measures of the relative vegetation health. These indices can be used to monitor areas where vegetation may be stressed, as a proxy to detect potential drought. The precipitation indicators present a global analysis of the absolute (mm) and relative (%) rainfall levels per dekad, in addition to the long-term average precipitation levels (mm).
