Saint Lucia FAPAR Vegetation Index Anomalies via VIIRS Imagery

Copernicus provides this geospatial dataset containing 10-day time composites of FAPAR anomalies for Saint Lucia derived from VIIRS satellite imagery. The data measures vegetation greenness and health on a scale of 0 to 1 to monitor agricultural drought impacts. It was last updated in March 2026.

Use Cases

• Detecting agricultural drought by identifying negative deviations in FAPAR anomaly values
• Monitoring vegetation productivity using the 0 to 1 dimensionless health scale
• Conducting environmental time-series analysis using the 10-day composite intervals

Strengths

• Derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors
• Standardized 10-day temporal resolution for consistent monitoring
• CC-BY license allows for open redistribution and commercial use

Limitations

• Raster format requires specialized GIS software for extraction and analysis
• Specific spatial resolution in meters is not explicitly defined in the metadata
• Lack of tabular metadata for specific administrative sub-regions
