Chad: 10-Day Copernicus FAPAR Vegetation Anomaly Composites

Copernicus provides 10-day time composite FAPAR anomaly data for Chad derived from the Visible Infrared Imaging Radiometer Suite (VIIRS). This geospatial dataset measures the greenness and health of vegetation to monitor agricultural drought impacts through biophysical radiation absorption metrics. The data is current as of March 2026 and is distributed in GEOTIFF format.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical baselines
• Monitoring vegetation productivity trends in Chad using 10-day composite intervals
• Assessing vegetation health by mapping values between 0 and 1 across different regions

Strengths

• 10-day time composite resolution from VIIRS sensors
• Standardized biophysical scale ranging from 0 to 1
• Open CC-BY license for unrestricted research use

Limitations

• Geographic scope is restricted to Chad
• Requires specialized GIS software to interpret GEOTIFF raster files
• No tabular metadata provided for specific pixel-level attributes
