Monthly Global NDVI at 5 km based on AVHRR product - Zenodo
WebLong-term monthly NDVI calculated through daily images of AVHRR ( NOAA/CDR/AVHRR/NDVI/V5 ), which were cloud screened and aggregated by percentile 90th on Google Earth Engine -GEE. All the images were exported from GEE to R environment where the follow procedures were executed on a pixel-basis: The normalized difference vegetation index (NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements, often from a space platform, assessing whether or not the target being observed contains live green vegetation.
