Nepal Subnational NDVI: Dekadal Vegetation Indices and Anomalies

Nepal sub-national vegetation health data aggregated every 10 days from NASA MODIS collection 6.1 satellite imagery. Produced by the World Food Programme (WFP), the dataset tracks NDVI indicators across administrative units to monitor agricultural conditions. The data is updated dekadally to provide near-real-time environmental monitoring.

Use Cases

• Detecting agricultural drought periods by monitoring the viq (NDVI anomaly) column
• Analyzing seasonal vegetation trends using the vim (10-day NDVI) time-series
• Validating sub-national crop health reports against the vim_lta historical average

Strengths

• Derived from NASA MODIS collection 6.1 satellite data
• Includes historical baselines via the vim_lta column
• Standardized Pcode references for administrative unit mapping

Limitations

• Spatial resolution is limited to administrative unit aggregates rather than raw pixels
• Data quality in the n_pixels column may vary based on seasonal cloud cover
