Mali Subnational NDVI: 10-Day Vegetation Indicators and Anomalies

Mali subnational vegetation indicators derived from NASA MODIS Collection 6.1 satellite data, aggregated by the World Food Programme (WFP) into 10-day intervals. The data provides dekadal NDVI values, long-term averages, and percentage anomalies for administrative units across the country.

Use Cases

• Monitoring drought conditions by analyzing the viq (NDVI anomaly) column across Mali regions
• Analyzing seasonal vegetation trends using vim and vim_lta time-series data
• Validating regional agricultural health by correlating n_pixels with reported vegetation density

Strengths

• Derived from NASA MODIS Collection 6.1 high-quality satellite data
• Includes Pcode references for standardized administrative unit joining
• Provides n_pixels column to verify the data density of each aggregate

Limitations

• Aggregation to administrative levels obscures local-scale vegetation variations
• Dependent on cloud-free satellite observations for accurate pixel counts
