American Samoa: 10-Day Copernicus FAPAR Vegetation Health Anomalies

Copernicus provides these 10-day time composite Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for American Samoa to monitor vegetation health. The data is derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) and measures biophysical absorption on a scale from 0 to 1. These records are used to detect and monitor the impacts of agricultural drought on regional productivity.

Use Cases

• Detecting agricultural drought impacts using FAPAR anomaly values
• Analyzing vegetation greenness trends over 10-day composite periods
• Mapping environmental productivity across American Samoa using GEOTIFF layers

Strengths

• Derived from standardized VIIRS satellite sensor data
• Consistent 10-day time composite intervals
• CC-BY license allows for open redistribution and academic use

Limitations

• Geographically restricted to American Samoa
• Requires specialized GIS software to process GEOTIFF file formats
• Lack of accompanying tabular metadata or attribute tables
