Lao PDR: FAPAR Vegetation Index Anomalies in 10-Day Composites

10-day time composite GEOTIFF files measuring the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies across Lao People's Democratic Republic. Produced by Copernicus using Visible Infrared Imaging Radiometer Suite (VIIRS) sensor data, this dataset monitors vegetation health and agricultural drought impacts. The data provides biophysical dimensionless quantities ranging from 0 to 1 to indicate absorption levels.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly values (0 to 1) across specific geographic coordinates
• Monitoring vegetation health trends using the 10-day time composite intervals to identify seasonal deviations
• Assessing crop productivity impacts by correlating GEOTIFF pixel values with known agricultural zones in Lao PDR

Strengths

• 10-day temporal resolution for high-frequency monitoring
• Standardized GEOTIFF format for GIS integration
• Derived from VIIRS satellite instrumentation

Limitations

• Optical sensor data is susceptible to cloud interference in tropical climates like Lao PDR
• Coarse spatial resolution inherent to VIIRS may miss micro-scale vegetation changes
• No accompanying tabular metadata provided for specific pixel-to-location mapping
