Austria FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

10-day time composite geospatial data measuring the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies across Austria. Produced by Copernicus using Visible Infrared Imaging Radiometer Suite (VIIRS) sensors, this dataset tracks vegetation health and agricultural drought indicators.

Use Cases

• Detecting agricultural drought by identifying negative FAPAR anomalies
• Monitoring seasonal vegetation health using the 0-1 absorption scale
• Analyzing crop productivity trends through 10-day composite time-series

Strengths

• Uses standardized VIIRS sensor data
• 10-day temporal resolution for near real-time monitoring
• Dimensionless 0-1 scale allows for consistent biophysical comparison

Limitations

• Geographically restricted to Austria
• GEOTIFF format requires specialized GIS software for analysis
• Cloud cover may affect sensor accuracy in specific composites
