Papua New Guinea: 10-Day VIIRS Vegetation Index Anomaly Maps

This geospatial dataset provides 10-day time composites of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Papua New Guinea, produced by Copernicus. The data utilizes Visible Infrared Imaging Radiometer Suite (VIIRS) sensor readings to measure vegetation greenness and health on a scale of 0 to 1. These anomalies serve as indicators for detecting and monitoring agricultural drought impacts on vegetation productivity.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical baselines
• Assessing vegetation health and greenness using the 0 to 1 dimensionless scale
• Conducting time-series analysis of vegetation productivity using 10-day composite intervals

Strengths

• 10-day temporal resolution for high-frequency monitoring
• Standardized biophysical quantity (FAPAR) for cross-region comparison
• Derived from VIIRS sensor data for consistent environmental observation

Limitations

• Requires specialized GIS software to interpret GEOTIFF raster formats
• Geographic scope is limited to a single country
• Lack of tabular metadata for specific pixel-level attributes
