Haiti FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides this geospatial dataset containing 10-day time composites of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Haiti. Derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors, the data tracks vegetation health and agricultural drought impacts. The records are delivered as GEOTIFF files representing biophysical values between 0 and 1.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical norms
• Monitoring vegetation health trends over 10-day intervals using VIIRS composites
• Correlating vegetation greenness with local precipitation data to assess crop stress

Strengths

• Uses VIIRS sensor data for high-frequency 10-day monitoring
• Standardized FAPAR scale (0 to 1) for consistent biophysical comparison
• CC-BY license allows for open redistribution and academic use

Limitations

• Raster format (GEOTIFF) requires specialized GIS software for analysis
• Geographic scope is restricted to Haiti
• Lack of tabular metadata or ground-truth labels for specific crop types
