Greece Subnational NDVI: Dekadal Vegetation Indicators and Anomalies

Greece subnational NDVI indicators derived from NASA MODIS collection 6.1 satellite data, aggregated by the World Food Programme (WFP). The data provides 10-day (dekadal) intervals for vegetation health monitoring across administrative units as recently as March 2026.

Use Cases

• Monitoring agricultural health by comparing current vim values against historical vim_lta averages
• Identifying drought or vegetation stress using the viq anomaly percentage column
• Analyzing regional vegetation trends across specific Pcode administrative boundaries

Strengths

• Derived from NASA Moderate Resolution Imaging Spectroradiometer (MODIS) collection 6.1
• Includes vim_lta (long-term average) for baseline comparisons
• Provides n_pixels column to verify the data density of each aggregate
• Uses standardized WFP Pcode references for administrative units

Limitations

• Spatial resolution is restricted to administrative aggregates rather than raw pixel-level data
• Data accuracy is subject to cloud cover interference common in optical satellite imagery
