Türkiye Subnational NDVI: 10-Day Vegetation Indicators and Anomalies

Offering dekadal (10-day) NDVI vegetation indicators for Türkiye, aggregated at sub-national administrative levels by the World Food Programme. It utilizes NASA MODIS collection 6.1 satellite data from Aqua and Terra sensors to track vegetation health, long-term averages, and anomalies.

Use Cases

• Monitoring regional agricultural health by comparing current NDVI (vim) against long-term averages (vim_lta)
• Identifying drought conditions using the NDVI anomaly percentage (viq) across different provinces
• Analyzing vegetation trends over time using WFP Pcode identifiers for geographic consistency

Strengths

• Derived from NASA MODIS collection 6.1 high-quality satellite imagery
• Includes historical baseline averages (vim_lta) for comparative analysis
• Provides pixel counts (n_pixels) to indicate the data density of each aggregate

Limitations

• Spatial resolution is restricted to administrative aggregates rather than raw pixel grids
• NDVI calculations are sensitive to persistent cloud cover during specific 10-day windows
