Eritrea FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides 10-day composite FAPAR anomaly data for Eritrea derived from the Visible Infrared Imaging Radiometer Suite (VIIRS). This geospatial dataset measures the fraction of absorbed photosynthetically active radiation to monitor vegetation health and agricultural drought impacts. The data is current as of March 2026 and is delivered in GEOTIFF format.

Use Cases

• Detecting agricultural drought by identifying negative FAPAR anomaly deviations
• Monitoring seasonal vegetation health trends using 10-day composite intervals
• Assessing regional crop productivity based on photosynthetically active radiation absorption levels

Strengths

• Utilizes high-quality Visible Infrared Imaging Radiometer Suite (VIIRS) sensor data
• Standardized biophysical scale (0 to 1) allows for consistent cross-temporal comparison
• Frequent 10-day temporal resolution for near real-time monitoring

Limitations

• Geographic scope is restricted to Eritrea
• Requires specialized GIS software to process and visualize GEOTIFF files
• Lack of tabular metadata for specific pixel-level statistical summaries
