Saint Kitts and Nevis: FAPAR Vegetation Health Anomalies via VIIRS

Copernicus provides 10-day composite GEOTIFF files measuring Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Saint Kitts and Nevis. These biophysical measurements, derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), track vegetation health and agricultural drought impacts. The records are updated through March 2026.

Use Cases

• Detecting agricultural drought by identifying negative FAPAR anomaly values
• Monitoring vegetation productivity trends using 10-day VIIRS composites
• Assessing environmental health through the 0-1 greenness absorption scale

Strengths

• Uses VIIRS sensor data for high-frequency monitoring
• Standardized 0 to 1 biophysical measurement scale
• 10-day composite intervals reduce cloud interference in vegetation assessment

Limitations

• Spatial resolution in meters per pixel is not specified in the metadata
• Geographic scope is limited strictly to Saint Kitts and Nevis
