Cayman Islands FAPAR Vegetation Anomalies: 10-Day VIIRS Composites

Copernicus provides 10-day time composite geospatial data measuring the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for the Cayman Islands. Derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), these records track vegetation health and agricultural drought impacts. The data is delivered in GEOTIFF format with values ranging from 0 to 1 to indicate absorption levels.

Use Cases

• Detecting agricultural drought by identifying negative FAPAR anomaly deviations in specific 10-day windows
• Monitoring seasonal vegetation health cycles across the Cayman Islands using VIIRS-derived greenness metrics
• Assessing the impact of extreme weather events on plant productivity by comparing pre- and post-event GEOTIFF layers

Strengths

• Uses VIIRS sensor data for consistent 10-day temporal resolution
• Standardized biophysical scale (0-1) for cross-region comparison
• CC-BY license allows for open redistribution and use

Limitations

• Geographic scope is restricted to the Cayman Islands
• Lack of tabular metadata makes it difficult to assess historical baseline periods without external documentation
• GEOTIFF format requires specialized GIS software for interpretation
