Sri Lanka FAPAR Vegetation Index Anomalies in 10-Day Composites

Ten-day time composite rasters of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies provide vegetation health metrics for Sri Lanka. Produced by Copernicus using Visible Infrared Imaging Radiometer Suite (VIIRS) sensors, the data uses a 0 to 1 scale to detect agricultural drought. The records are current as of March 2026.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly values to identify deviations from normal vegetation health
• Monitoring seasonal vegetation productivity using the 10-day time composite GEOTIFF files
• Mapping regional crop stress across Sri Lanka by processing VIIRS-derived geospatial rasters

Strengths

• 10-day time composite frequency for temporal monitoring
• Standardized FAPAR scale ranging from 0 to 1
• Utilizes Visible Infrared Imaging Radiometer Suite (VIIRS) sensor data

Limitations

• Geographic scope is restricted to Sri Lanka
• GEOTIFF format requires specialized GIS software for interpretation
• No tabular metadata provided for individual pixel attributes
