Guinea: 10-Day FAPAR Vegetation Index Anomalies from VIIRS

This geospatial dataset provides 10-day composite FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) anomalies for Guinea, produced by Copernicus using VIIRS sensor data. Updated through March 2026, the data measures vegetation greenness and health on a scale of 0 to 1 to monitor agricultural drought impacts. The records are delivered as GEOTIFF raster files suitable for environmental and agricultural monitoring.

Use Cases

• Detecting agricultural drought by identifying negative deviations in FAPAR anomaly values
• Assessing seasonal vegetation growth cycles using 10-day composite intervals
• Mapping spatial distribution of vegetation health across Guinea's ecological zones

Strengths

• Derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) for high-quality sensing
• Standardized 0-1 dimensionless scale for vegetation health assessment
• High-frequency 10-day temporal resolution for drought monitoring

Limitations

• Geographic scope is strictly limited to Guinea
• Requires GIS software or specialized libraries to process GEOTIFF raster formats
• Lack of tabular metadata or specific column definitions beyond the raster values
