Ghana FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides 10-day composite FAPAR anomaly data for Ghana derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors. These geospatial records measure the fraction of absorbed photosynthetically active radiation to monitor vegetation health and detect agricultural drought impacts. The data is current as of March 2026 and follows a standardized biophysical measurement scale.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from baseline values
• Monitoring vegetation health trends across Ghana using 10-day composite intervals
• Correlating VIIRS-derived greenness with local crop yield reports to predict food security

Strengths

• Uses VIIRS sensor data for high-frequency 10-day composites
• Standardized FAPAR scale (0 to 1) for consistent biophysical monitoring
• CC-BY license allows for open redistribution and commercial use

Limitations

• Geographic scope is restricted to Ghana
• Raster format requires specialized GIS software for extraction and analysis
• Specific pixel resolution and historical start date are not specified in the metadata
