Land Long Term Data Record (LTDR): NDVI and Reflectance from AVHRR
Listed in NASA Earthdata CMR
LTDR is a NASA-funded REASoN project to produce a consistent long term data set from AVHRR and MODIS instruments for climate studies.
Description
Data products consist of NOAA/AVHRR surface reflectance and Normalized Difference Vegetation Index (NDVI) from 1980-2004 at 0.05 degree resolution.
