South Sudan FAPAR Vegetation Index Anomalies via 10-Day VIIRS Composites

Copernicus provides 10-day time composite FAPAR anomaly data for South Sudan derived from the Visible Infrared Imaging Radiometer Suite (VIIRS). This geospatial dataset measures vegetation greenness and health to monitor agricultural drought impacts, with records updated through March 2026.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical norms
• Monitoring vegetation health trends over 10-day intervals to identify seasonal shifts
• Assessing crop productivity impacts in South Sudan using VIIRS-derived biophysical indices

Strengths

• High temporal resolution with 10-day composites
• Derived from standardized VIIRS sensor data
• Standardized biophysical scale (0 to 1) for comparability

Limitations

• Geographic restriction to South Sudan only
• Requires specialized GIS software to interpret GEOTIFF format
• Lack of tabular metadata for pixel-level ground truth
