Equatorial Guinea Subnational NDVI: 10-Day Vegetation Anomaly Data

Dekadal (10-day) NDVI indicators for Equatorial Guinea aggregated by sub-national administrative units, produced by the World Food Programme. Derived from NASA MODIS collection 6.1 satellite imagery, the records track vegetation health through current values, long-term averages, and percentage anomalies.

Use Cases

• Monitoring agricultural health by comparing `vim` against `vim_lta` to identify drought conditions
• Analyzing temporal vegetation trends using the 10-day dekadal intervals
• Correlating `viq` (anomaly %) with food security outcomes at the sub-national level

Strengths

• Utilizes NASA MODIS collection 6.1 satellite data from both Aqua and Terra platforms
• Includes Pcode references for standardized geospatial joining
• Provides `n_pixels` to indicate the statistical weight of each aggregate

Limitations

• Aggregated at the sub-national level, losing fine-grained pixel-level spatial variance
• Satellite-derived NDVI readings are susceptible to interference from tropical cloud cover
