Sudan FAPAR Vegetation Index Anomalies in 10-Day Composites

10-day composite GEOTIFF imagery of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Sudan, produced by Copernicus. The data measures vegetation greenness and health on a scale of 0 to 1 to monitor agricultural drought impacts. These records are derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) and were last updated in March 2026.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical baselines
• Monitoring seasonal vegetation productivity trends using the 10-day composite cycles
• Assessing crop health across Sudan's agricultural zones via the 0-1 absorption scale

Strengths

• Derived from standardized VIIRS satellite sensor data
• Dimensionless 0-1 scale allows for consistent cross-region comparison
• 10-day temporal resolution captures rapid changes in vegetation health

Limitations

• Geographic scope is limited to Sudan
• Requires GIS-specialized software to interpret GEOTIFF formats
• Lack of tabular metadata for specific pixel-level ground truth
