Dominica FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides 10-day time composite GEOTIFF files of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Dominica. This data, derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors, measures vegetation greenness and health to monitor agricultural drought impacts. The records are updated through March 2026.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical norms
• Monitoring vegetation health trends in Dominica using 10-day time composites
• Assessing crop productivity impacts based on the 0 to 1 FAPAR scale

Strengths

• High temporal resolution with 10-day composite intervals
• Standardized FAPAR scale (0 to 1) for consistent vegetation health assessment
• Derived from VIIRS sensor data for reliable environmental monitoring

Limitations

• Geographic restriction to Dominica only
• GEOTIFF format requires specialized GIS software for interpretation
• Lack of tabular metadata for individual pixel values
