Japan Subnational NDVI: Dekadal Vegetation Indicators and Anomalies

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

Use Cases

• Monitoring agricultural health trends by analyzing the viq (NDVI anomaly) column over time
• Establishing environmental baselines for Japan using the vim_lta long-term average
• Assessing the statistical reliability of regional aggregates using the n_pixels count

Strengths

• Derived from NASA MODIS collection 6.1 high-resolution satellite data
• Includes Pcode references for standardized geospatial joining with other WFP datasets
• Provides n_pixels column to indicate the data density of each aggregate

Limitations

• Aggregated at the administrative level, which obscures sub-unit spatial variance
• Geospatial boundaries are limited to WFP-specific administrative definitions
