Réunion FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides this geospatial dataset of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Réunion, updated through March 2026. The data consists of 10-day time composites derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) to monitor vegetation health and agricultural drought.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical norms
• Monitoring vegetation productivity in Réunion using 10-day composite GEOTIFFs
• Assessing the impact of climate events on greenness levels via VIIRS-derived indices

Strengths

• Derived from high-resolution VIIRS sensor data
• Standardized 0-1 dimensionless scale for vegetation health
• 10-day temporal resolution for monitoring rapid drought onset

Limitations

• Geographic scope is limited strictly to Réunion
• Potential for cloud interference in optical VIIRS imagery affecting data quality
• Lack of tabular metadata or specific column descriptions
