Niger Vegetation Health: 10-Day FAPAR Anomaly GeoTIFFs

A source of 10-day time composite geospatial records of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Niger, 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 values are delivered as dimensionless quantities ranging from 0 to 1 to represent photosynthetic absorption levels.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical norms
• Monitoring vegetation health trends using the 0-1 absorption scale across different ecological zones
• Assessing crop productivity impacts in Niger based on 10-day composite intervals

Strengths

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

Limitations

• Geographic scope is restricted to Niger
• Requires GIS software to process and interpret GeoTIFF raster formats
• Lack of tabular metadata for specific pixel-level attributes
