Senegal FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides this geospatial dataset of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Senegal. The data is derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) and delivered as 10-day time composites. These biophysical measurements range from 0 to 1 to track vegetation health and agricultural drought impacts.

Use Cases

• Detecting agricultural drought by identifying negative FAPAR anomaly values in specific regions
• Monitoring seasonal vegetation growth cycles using 10-day VIIRS time composites
• Assessing land productivity trends by analyzing the 0-1 dimensionless absorption scale over multiple years

Strengths

• Derived from VIIRS sensor data for consistent 10-day temporal resolution
• Standardized biophysical scale (0 to 1) allows for direct comparison across different regions
• Produced by Copernicus, ensuring high-authority Earth observation standards

Limitations

• Geographic scope is limited exclusively to Senegal
• Requires GIS software to process and interpret GEOTIFF raster layers
• Lack of tabular metadata or specific column headers for non-spatial attributes
