Taiwan FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

This geospatial dataset provides 10-day composite FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) anomalies for Taiwan, produced by Copernicus using VIIRS sensor data. The records measure vegetation health and greenness relative to historical norms to identify agricultural drought impacts. The data is delivered as GEOTIFF files with values ranging from 0 to 1.

Use Cases

• Monitoring agricultural drought by analyzing FAPAR anomaly deviations from historical baselines
• Assessing vegetation health and productivity using the 0-1 dimensionless absorption scale
• Time-series analysis of crop growth cycles using the 10-day composite intervals

Strengths

• Uses VIIRS sensor data for high-frequency 10-day composites
• Standardized FAPAR scale (0 to 1) for cross-regional comparison
• Open CC-BY license allows for commercial and academic reuse

Limitations

• Lack of tabular metadata or specific column definitions in the source
• Potential for cloud cover interference in optical sensor readings
• Geographic scope is limited strictly to Taiwan
