Heard Island and McDonald Islands: 10-Day VIIRS FAPAR Vegetation Anomalies

Copernicus provides 10-day time composite GEOTIFF files measuring the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Heard Island and McDonald Islands. This geospatial data, derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), monitors vegetation health and agricultural drought impacts. The dataset was last updated in March 2026.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly values across the islands
• Monitoring vegetation health trends using the 10-day time composite GEOTIFF layers
• Assessing environmental impacts on sub-Antarctic flora by correlating VIIRS sensor data with local climate events

Strengths

• Standardized FAPAR scale (0-1) for biophysical monitoring
• 10-day time composite resolution from VIIRS sensors
• GEOTIFF format for immediate GIS application

Limitations

• Geographically restricted to a small sub-Antarctic island group
• Lack of tabular metadata or specific column definitions
• Satellite-derived data may be affected by persistent cloud cover in the region
