Iceland FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides 10-day time composite geospatial data of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Iceland. Derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), this data monitors vegetation health and agricultural drought impacts. The records are updated as recently as March 2026 and utilize a standardized dimensionless scale.

Use Cases

• Detecting agricultural drought by monitoring FAPAR anomaly deviations from baseline health
• Assessing vegetation greenness using the 0 to 1 dimensionless scale across different seasons
• Mapping temporal health trends across Iceland's landscape via GEOTIFF rasters

Strengths

• Derived from VIIRS sensor data
• 10-day time composite frequency
• Standardized FAPAR scale (0 to 1)
• CC-BY licensed for open use

Limitations

• Geographically restricted to Iceland
• Requires GIS software to process GEOTIFF raster files
• Lack of tabular metadata for individual pixels
