Normalized Difference Vegetation Index

Displayed global Mercator image representing vegetation coverage derived from normalized difference vegetation index terrestrial product.

This dataset provides a high quality Climate Data Record (CDR) of Normalized Differential Vegetation Index (NDVI).

The NDVI CDR summarizes the measurement of surface vegetation coverage activity. The surface reflectance calculations in the red and the near infrared spectral bands derived from Advanced Very High Resolution Radiometer (AVHRR) provide NDVI values. The NDVI CDR produces daily output on a 0.05° by 0.05° grid, from 1981 to present. This consistent, long-term record of remotely sensed vegetation observations allows scientists to characterize the health of vegetation in different regions across the world.
