NOAA Climate Data Record (CDR) of AVHRR Normalized Difference Vegetation Index (NDVI), Version 5
Normalized Difference Vegetation Index
This dataset contains gridded daily Normalized Difference Vegetation Index (NDVI) derived from the NOAA Climate Data Record (CDR) of Advanced Very High Resolution Radiometer (AVHRR) Surface Reflectance. The data record spans from 1981 to 10 days before the present using data from eight NOAA polar orbiting satellites: NOAA-7, -9, -11, -14, -16, -17, -18 and -19. The data are projected on a 0.05 degree x 0.05 degree global grid. This dataset is one of the Land Surface CDR Version 5 products produced by the NASA Goddard Space Flight Center (GSFC) and the University of Maryland (UMD). Improvements for Version 5 include using the improved surface reflectance data, correcting the data for known errors in time, latitude, and longitude variables, as well as improvements in the global and variable attribute definitions. The dataset is in the netCDF-4 file format following ACDD and CF Conventions. The dataset is accompanied by algorithm documentation, data flow diagram and source code for the NOAA CDR Program.

Purpose | This dataset was produced to provide a high quality Climate Data Record (CDR) of Normalized Differential Vegetation Index (NDVI) for detecting drought-stressed regions, forecasting agricultural yields, and forestry and crop management. 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 degree by 0.05 degree global 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. |
