Guam Vegetation Health: 10-Day FAPAR Anomaly Geospatial Data

Copernicus provides 10-day composite FAPAR anomaly data for Guam derived from the Visible Infrared Imaging Radiometer Suite (VIIRS). This geospatial dataset measures vegetation greenness and health to monitor agricultural drought impacts, with records updated through March 2026.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical norms
• Monitoring vegetation productivity using the 0-1 greenness scale
• Assessing environmental health impacts in Guam over 10-day intervals

Strengths

• Derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors
• Standardized 0-1 dimensionless scale for vegetation health
• 10-day temporal resolution for monitoring seasonal changes

Limitations

• Geographically restricted to Guam
• Raster format requires specialized GIS software for processing
• Lack of specific tabular metadata for individual land parcels
