Comoros Subnational NDVI: Dekadal Vegetation Indices and Anomalies

Dekadal NDVI indicators for Comoros aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme, this dataset provides 10-day vegetation health metrics including long-term averages and anomalies. The data is current as of March 2026 and utilizes WFP-standardized administrative boundaries.

Use Cases

• Assessing crop stress by analyzing the NDVI anomaly percentage (viq) across dekads
• Comparing current vegetation levels (vim) against historical baselines (vim_lta) for food security monitoring
• Mapping regional environmental changes using Pcode identifiers to link with geographic shapefiles

Strengths

• Derived from NASA MODIS collection 6.1 Aqua and Terra satellite data
• Includes Pcode references for interoperability with WFP administrative boundaries
• Provides n_pixels count to indicate the data density for each aggregate

Limitations

• Aggregated at the sub-national level, masking localized vegetation variations within units
• Dependent on cloud-free satellite observations which may affect the n_pixels count in certain periods
