Armenia Subnational NDVI: Dekadal Vegetation Indicators and Anomalies

Giving access to dekadal (10-day) Normalized Difference Vegetation Index (NDVI) indicators for Armenia, aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme (WFP), the records include current NDVI values, long-term averages, and percentage anomalies updated through March 2026.

Use Cases

• Monitoring agricultural health by comparing current NDVI (vim) against the long-term average (vim_lta)
• Identifying drought conditions or vegetation stress using the NDVI anomaly percentage (viq)
• Analyzing temporal vegetation trends across different Armenian sub-regions using the dekadal time-series

Strengths

• Uses NASA MODIS collection 6.1 high-quality satellite data
• Includes long-term average (vim_lta) for historical baseline comparison
• Provides pixel counts (n_pixels) to indicate the data density of each aggregate

Limitations

• Spatial resolution is limited to administrative unit aggregates rather than raw pixel-level data
• Geographic boundaries are strictly tied to WFP-specific Pcode references
