Mali Vegetation Index Anomaly: 10-Day VIIRS FAPAR Composites

Copernicus produces 10-day time composite FAPAR anomaly data for Mali using the Visible Infrared Imaging Radiometer Suite (VIIRS). This geospatial dataset measures the fraction of absorbed photosynthetically active radiation to detect and monitor agricultural drought impacts on vegetation growth.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly pixel values
• Monitoring vegetation productivity trends using 10-day VIIRS composites
• Assessing environmental health in Mali via greenness index deviations

Strengths

• 10-day temporal resolution for frequent monitoring
• Uses VIIRS (Visible Infrared Imaging Radiometer Suite) sensor data
• Standardized 0 to 1 dimensionless scale for biophysical assessment

Limitations

• Geographic scope is restricted to Mali
• Requires specialized GIS software to interpret GEOTIFF raster data
• Temporal coverage start date is not specified in the metadata
