Description
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
Provenance
Source
World Food Programme (WFP) using NASA MODIS (Aqua and Terra) collection 6.1
Collection Method
Satellite sensor data aggregation
Freshness
Updated as of March 2026.
Geography
Armenia (sub-national level)
