Eswatini FAPAR Vegetation Index Anomalies via 10-Day VIIRS Composites

Copernicus provides 10-day time composite GEOTIFF files measuring the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Eswatini. Derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors, these records monitor vegetation health and agricultural drought impacts. The data captures biophysical greenness as a dimensionless quantity ranging from 0 to 1.

Use Cases

• Detecting agricultural drought impacts by analyzing FAPAR anomaly deviations in 10-day intervals
• Assessing vegetation health using the 0-1 dimensionless greenness scale
• Integrating VIIRS-based raster data into regional environmental risk and climate models

Strengths

• 10-day temporal resolution for granular time-series analysis
• Standardized FAPAR metric (0-1 range) for consistent health assessment
• Utilizes VIIRS sensor data for high-quality satellite imagery

Limitations

• Geographic scope is restricted to Eswatini
• Optical sensor data is subject to interference from cloud cover
• Lack of accompanying tabular metadata for specific pixel-level attributes
