Sao Tome and Principe: 10-Day VIIRS Vegetation FAPAR Anomalies

Copernicus provides 10-day composite VIIRS satellite imagery of FAPAR anomalies for Sao Tome and Principe. These GEOTIFF files measure vegetation health and agricultural drought impacts through biophysical absorption values ranging from 0 to 1. The data is updated through March 2026 and serves as a primary indicator for monitoring vegetation productivity.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical norms
• Monitoring vegetation health and productivity using the 0-1 absorption scale
• Conducting time-series analysis of environmental changes using the 10-day composite intervals

Strengths

• Uses VIIRS sensor data for high-frequency 10-day composites
• Standardized FAPAR scale (0 to 1) for consistent biophysical monitoring
• Geospatial GEOTIFF format allows for direct integration into GIS software

Limitations

• Geographically restricted to Sao Tome and Principe
• Lacks tabular metadata or specific column descriptions in the source
• Resolution of VIIRS imagery may be insufficient for hyper-local or individual plot analysis
