Cocos (Keeling) Islands: 10-Day Copernicus FAPAR Vegetation Anomalies

A source of 10-day time composite geospatial rasters of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for the Cocos (Keeling) Islands. Produced by Copernicus using Visible Infrared Imaging Radiometer Suite (VIIRS) sensor data, the records track vegetation health through March 2026. The data measures biophysical absorption on a dimensionless scale from 0 to 1 to identify agricultural drought impacts.

Use Cases

• Detecting agricultural drought impacts by monitoring FAPAR anomaly deviations from historical baselines
• Assessing vegetation health and greenness using the 0-1 dimensionless absorption scale
• Analyzing seasonal growth productivity cycles in tropical island environments

Strengths

• Derived from VIIRS sensor data for consistent 10-day temporal resolution
• Standardized biophysical scale (0 to 1) allows for cross-region comparison
• GEOTIFF format supports immediate integration into GIS software

Limitations

• Geographic scope is restricted to the Cocos (Keeling) Islands
• Optical sensor data is subject to interference from cloud cover
• Lack of tabular metadata or attribute tables for non-spatial analysis
