Kiribati FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Supplying 10-day composite GEOTIFF rasters of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Kiribati, produced by Copernicus. The data is derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) to monitor vegetation health and agricultural drought impacts. The records are updated through March 2026, offering a high-frequency temporal view of biophysical changes.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from the 0-1 baseline
• Monitoring vegetation health trends across Kiribati using 10-day VIIRS composites
• Correlating photosynthetic activity with local climate events using GEOTIFF spatial data

Strengths

• Uses VIIRS sensor data for high-frequency 10-day temporal resolution
• Standardized FAPAR scale (0 to 1) allows for consistent biophysical comparison
• Geospatial GEOTIFF format enables direct integration with GIS software

Limitations

• Geographic scope is limited strictly to Kiribati
• Requires specialized GIS software or libraries to interpret pixel-level data
• Lack of accompanying tabular metadata for specific island-level statistics
