Cambodia FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

10-day time composite geospatial layers measuring Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies across Cambodia. Produced by Copernicus using Visible Infrared Imaging Radiometer Suite (VIIRS) sensor data, these records track vegetation health and agricultural drought impacts. The data is updated on a decadal (10-day) cycle to monitor deviations in vegetation greenness.

Use Cases

• Detecting agricultural drought by identifying pixels with low FAPAR anomaly values
• Monitoring seasonal vegetation productivity trends using the 10-day composite layers
• Assessing crop health by comparing current FAPAR values against historical baselines in GEOTIFF format

Strengths

• 10-day temporal resolution for frequent monitoring
• Derived from standardized VIIRS sensor data
• Dimensionless 0-1 scale allows for cross-region vegetation health comparison

Limitations

• Geographic scope is limited strictly to Cambodia
• Optical sensor data is subject to interference from cloud cover in tropical climates
• Lack of tabular metadata or attribute tables beyond the raster values
