Portugal FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

10-day composite geospatial measurements of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies across Portugal. Produced by Copernicus using Visible Infrared Imaging Radiometer Suite (VIIRS) sensors, the data tracks vegetation health and agricultural drought impacts. The records are current through March 2026.

Use Cases

• Identifying agricultural drought zones by filtering for low FAPAR anomaly values
• Analyzing vegetation productivity cycles using the 10-day composite intervals
• Correlating vegetation health with local climate data using the GEOTIFF spatial coordinates

Strengths

• 10-day temporal resolution for high-frequency environmental monitoring
• Standardized GEOTIFF format for immediate GIS application
• Utilizes VIIRS sensor data for consistent biophysical measurement

Limitations

• Geographic restriction to Portugal only
• Lack of accompanying tabular metadata for statistical summaries
• Optical sensor data is subject to interference from cloud cover
