Quality of normalized difference vegetation index (Africa and Near East - Long Term - 250m) - WaPOR v2

The long-term NDVI quality layer is produced as a summary of the quality for the entire time period (2009 to 2022). Pixel values indicate the percentage of good NDVI observations over the entire time period. **Data publication:** 2020-01-01 **Supplemental Information:** No data value: 255 Unit: Percentage (%) Scale Factor : 1.0 Map code : L2-QUAL-NDVI-LT **Citation:** FAO 2018.

Pixel values indicate the percentage of good NDVI observations over the entire time period. While the dekadal NDVI Quality layer shows the quality of the data for a specific time of year, the long-term NDVI quality layer has been added to give users a quick overview of the areas that tend to suffer more cloud cover. Until December 2019 the base input layers (NDVI, albedo, and fAPAR) for the Level 2 (100m) products were derived from the Proba-V satellite. Proba-V was decommissioned in June 2020. From January 2020 onwards the base input layers of NDVI, albedo and fAPAR for level 2 are derived from the Copernicus Sentinel-2 mission. **Resource constraints:** Creative Commons Attribution 4.0 International (CC BY 4.0) **Online resources:** Download the data from Google Cloud Storage
