avhrr cdr daily land ndvi noaa


The NOAA Climate Data Record (CDR) of AVHRR Normalized Difference Vegetation Index (NDVI) contains gridded daily NDVI derived from the NOAA AVHRR Surface Reflectance product. It provides a measurement of surface vegetation coverage activity, gridded at a resolution of 0.05° and computed globally over land surfaces.

Known issues with this dataset include:

  • TIMEOFDAY variable contains values that are too large by 1 day

  • Latitude values are not correctly associated with the center of the grid cell, error is < 0.002 degrees

  • Longitude values are not correctly associated with the center of the grid cell, error is < 0.02 degrees

See technical note from the data provider.

Provider's note: the orbital drift of N-19 (the last NOAA satellite carrying the AVHRR sensor) began to severely degrade the retrieved product quality. Therefore, VIIRS is now the primary sensor being used for these products from 2014-present.

The NOAA CDR Program's official distribution point for CDRs is NOAA's National Climatic Data Center which provides sustained, open access and active data management of the CDR packages and related information in keeping with the United States' open data policies and practices as described in the President's Memorandum on "Open Data Policy" and pursuant to the Executive Order of May 9, 2013, "Making Open and Machine Readable the New Default for Government Information". In line with these policies, the CDR data sets are nonproprietary, publicly available, and no restrictions are placed upon their use.
