Somalia Vegetation Index Anomaly: 10-Day VIIRS FAPAR Composites

Copernicus provides these 10-day composite FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) anomaly maps for Somalia to monitor vegetation health. The data, derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), was last updated in March 2026. It serves as a primary indicator for detecting agricultural drought impacts on plant productivity.

Use Cases

• Identifying agricultural drought zones by mapping FAPAR anomaly deviations from the mean
• Monitoring seasonal vegetation growth cycles using 10-day composite intervals
• Quantifying photosynthetic activity levels across Somali rangelands via the 0-1 absorption scale

Strengths

• 10-day temporal resolution
• Standardized FAPAR scale (0-1)
• Derived from VIIRS satellite imagery

Limitations

• Restricted to Somalia geographic boundaries
• Potential sensor interference from cloud cover
• Requires specialized GIS software for raster analysis
