Argentina Subnational NDVI: Dekadal Vegetation Indices and Anomalies

WFP-produced dekadal NDVI indicators for Argentina's sub-national administrative units derived from NASA MODIS collection 6.1 satellite data. The dataset provides 10-day vegetation indices, long-term averages, and percentage anomalies for monitoring agricultural health.

Use Cases

• Analyzing vegetation health trends using the viq anomaly percentage
• Comparing current vegetation levels against historical baselines via vim_lta
• Validating administrative-level agricultural reports using the n_pixels count

Strengths

• Derived from NASA MODIS collection 6.1 satellite data
• Includes long-term average (vim_lta) for baseline comparison
• Provides pixel counts (n_pixels) to indicate aggregation reliability

Limitations

• Aggregated at the administrative level, losing granular spatial variation within units
• Dependent on cloud-free satellite observations for accurate NDVI values
