Argentina FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus produces these 10-day time composites of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Argentina. The data utilizes Visible Infrared Imaging Radiometer Suite (VIIRS) sensors to measure vegetation greenness on a 0 to 1 scale for drought monitoring.

Use Cases

• Detecting agricultural drought by identifying negative deviations in FAPAR anomaly values.
• Mapping vegetation health across Argentina using 10-day composite GeoTIFF layers.
• Analyzing photosynthetic activity trends using the 0 to 1 dimensionless absorption scale.

Strengths

• 10-day composite frequency for high-cadence monitoring
• VIIRS sensor-based biophysical measurements
• Open CC-BY license for research and commercial use

Limitations

• Unknown spatial resolution for the GeoTIFF files
• Absence of historical start date in the provided metadata
• Dimensionless values (0-1) require external reference for absolute biomass estimation
