Japan FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides these 10-day time composite GEOTIFF rasters measuring Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies across Japan. The data utilizes the Visible Infrared Imaging Radiometer Suite (VIIRS) to track vegetation greenness and agricultural drought indicators. The records are formatted as dimensionless values ranging from 0 to 1 to represent absorption levels.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly values ranging from 0 to 1
• Monitoring seasonal vegetation health trends using the 10-day time composite rasters
• Assessing plant productivity impacts by comparing VIIRS-derived greenness metrics over time

Strengths

• 10-day temporal resolution for frequent vegetation monitoring
• Standardized FAPAR scale (0 to 1) for consistent health assessment
• Utilizes VIIRS satellite sensor data for high-quality observation

Limitations

• Restricted to Japan's geographic boundaries
• GEOTIFF format requires specialized geospatial software for analysis
• Temporal lag inherent in 10-day composite processing
