Vietnam FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides these 10-day time composites of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Vietnam. The data utilizes Visible Infrared Imaging Radiometer Suite (VIIRS) sensors to measure vegetation greenness on a scale of 0 to 1. Records are current through March 2026.

Use Cases

• Identifying agricultural drought zones using FAPAR anomaly pixel values
• Analyzing vegetation growth cycles via 10-day composite sequences
• Correlating FAPAR absorption levels with crop productivity metrics

Strengths

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

Limitations

• Geographic restriction to Vietnam
• Cloud cover interference in optical imagery
• Unknown spatial resolution
