Thailand FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides 10-day time composite FAPAR anomaly data for Thailand derived from the Visible Infrared Imaging Radiometer Suite (VIIRS). This geospatial dataset measures vegetation greenness and health to monitor agricultural drought impacts through March 2026. It utilizes a dimensionless scale from 0 to 1 to represent the fraction of photosynthetically active radiation absorbed by vegetation.

Use Cases

• Monitoring agricultural drought impacts by comparing FAPAR anomaly values over time
• Assessing vegetation health across Thailand using 10-day composite intervals
• Spatial mapping of vegetation stress using GEOTIFF coordinate systems

Strengths

• 10-day temporal resolution
• Derived from VIIRS sensor data
• Standardized 0-1 dimensionless scale

Limitations

• Requires GIS software to process GEOTIFF files
• Optical sensor data may be affected by cloud cover in tropical regions
• Lack of tabular metadata for specific crop types
