Nepal FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides 10-day composite FAPAR anomaly data for Nepal derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors to monitor vegetation health. This geospatial dataset tracks agricultural drought impacts using dimensionless values ranging from 0 to 1, representing the fraction of absorbed photosynthetically active radiation. The data is updated frequently to support environmental monitoring and food security assessments.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from 1.0
• Monitoring seasonal vegetation growth cycles in Nepal using 10-day composites
• Assessing crop productivity based on photosynthetically active radiation absorption levels

Strengths

• 10-day temporal resolution for high-frequency monitoring
• Derived from standardized VIIRS sensor data
• Uses a standardized 0-1 dimensionless scale for vegetation health

Limitations

• Requires GIS software to process GEOTIFF format
• Geographically restricted to Nepal
• Lack of tabular metadata for specific administrative regions
