Angola FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

A source of 10-day composite FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) anomaly data for Angola, produced by Copernicus using Visible Infrared Imaging Radiometer Suite (VIIRS) sensors. The data measures vegetation greenness and health on a scale of 0 to 1 to monitor agricultural drought impacts.

Use Cases

• Monitoring agricultural drought by analyzing FAPAR anomaly deviations
• Assessing vegetation health using the 0 to 1 absorption scale
• Time-series analysis of crop productivity via 10-day composite intervals

Strengths

• Standardized 0-1 biophysical scale
• 10-day temporal resolution
• Derived from VIIRS satellite sensors

Limitations

• Geographically restricted to Angola
• Potential for cloud interference in optical sensor data
• No tabular metadata provided
