Timor-Leste FAPAR Vegetation Anomalies: 10-Day VIIRS Composites

This geospatial dataset provides 10-day time composite FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) anomalies for Timor-Leste, produced by Copernicus using Visible Infrared Imaging Radiometer Suite (VIIRS) data. The records measure vegetation health and greenness on a scale of 0 to 1 to monitor agricultural drought impacts. The data is updated through March 2026.

Use Cases

• Monitoring agricultural drought by identifying negative FAPAR anomaly values
• Analyzing vegetation productivity cycles using 10-day composite intervals
• Mapping spatial extent of plant stress across Timor-Leste using GEOTIFF raster data

Strengths

• 10-day temporal resolution for high-frequency monitoring
• Standardized biophysical scale (0 to 1) for vegetation health
• Utilizes VIIRS sensor data for consistent satellite imagery

Limitations

• Requires GIS software to interpret GEOTIFF raster formats
• Potential for data gaps due to cloud interference with optical sensors in tropical climates
