Brazil FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Offering 10-day time composite geospatial data of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Brazil, produced by Copernicus. Derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), the data monitors vegetation health and agricultural drought impacts through a dimensionless quantity ranging from 0 to 1.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly values below historical thresholds
• Monitoring vegetation productivity trends using the 10-day time composite layers
• Assessing crop health across different Brazilian regions by mapping the 0-1 absorption scale

Strengths

• Derived from high-resolution VIIRS sensor data
• Standardized 0-1 dimensionless scale for vegetation health
• 10-day temporal resolution for monitoring rapid drought onset

Limitations

• Lack of tabular metadata or specific column definitions
• Geographic scope limited to Brazil
• Requires GIS software to process GEOTIFF formats
