Togo FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

A source of 10-day composite Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Togo, produced by Copernicus. Derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), the data measures vegetation health on a scale of 0 to 1 to identify agricultural drought impacts. The records are maintained with updates extending through March 2026.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical baselines
• Monitoring seasonal vegetation health trends using the 10-day composite intervals
• Assessing regional crop productivity potential based on the 0-1 absorption scale

Strengths

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

Limitations

• Geographic scope is restricted solely to Togo
• Resolution of the VIIRS sensor may be too coarse for field-level analysis of smallholder plots
• Lack of tabular metadata or attribute tables beyond the raster values
