16-Day Vegetation Anomaly

The map is based on the Normalized Difference Vegetation Index (NDVI), a measure of how plant leaves absorb visible light and reflect infrared light. Drought-stressed vegetation reflects more visible light and less infrared than healthy vegetation. The vegetation index helps us see how much or how little live plant material is out there.
