Congo: 10-Day VIIRS Vegetation Index (FAPAR) Anomalies

A source of 10-day time composite geospatial imagery of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for the Congo, produced by Copernicus. Derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors, the data monitors vegetation health and agricultural drought impacts through March 2026. The records are delivered as dimensionless values ranging from 0 to 1 to indicate absorption levels.

Use Cases

• Detecting agricultural drought by identifying FAPAR anomaly values significantly below historical norms
• Monitoring vegetation productivity trends using the 10-day VIIRS composite intervals
• Assessing environmental health in the Congo region through photosynthetic absorption rates

Strengths

• Derived from standardized VIIRS sensor data
• 10-day temporal resolution allows for seasonal trend monitoring
• Uses a standardized 0-1 dimensionless scale for vegetation health

Limitations

• Geographic scope is limited to the Congo
• Requires specialized GIS software to process and interpret GEOTIFF files
• Lack of tabular metadata or specific attribute columns beyond the raster values
