Trinidad and Tobago: 10-Day VIIRS Vegetation FAPAR Anomalies

Copernicus provides this geospatial data containing 10-day time composites of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Trinidad and Tobago. Derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), these records monitor vegetation health and agricultural drought impacts through March 2026. The data is delivered as GEOTIFF rasters representing biophysical dimensionless quantities ranging from 0 to 1.

Use Cases

• Detecting agricultural drought by identifying negative FAPAR anomaly deviations in specific regions
• Monitoring seasonal vegetation health cycles using 10-day VIIRS composite intervals
• Assessing environmental impact on photosynthetic productivity across different land cover types

Strengths

• Utilizes VIIRS sensor data for consistent 10-day temporal resolution
• Standardized FAPAR anomaly metric (0-1 scale) for objective health assessment
• GEOTIFF format allows for immediate integration into GIS software

Limitations

• Geographic restriction to Trinidad and Tobago prevents regional Caribbean analysis
• Requires specialized GIS tools or libraries to extract numerical values from rasters
• Lack of ground-truth tabular labels for specific crop types
