Northern Mariana Islands: 10-Day VIIRS Vegetation Index Anomalies

Copernicus provides this geospatial dataset containing 10-day time composites of FAPAR anomalies for the Northern Mariana Islands. Derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensors, the data measures vegetation greenness and health to monitor agricultural drought impacts. The records are updated through March 2026 and utilize a standardized biophysical scale from 0 to 1.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical baselines
• Monitoring vegetation health trends across the islands using the 10-day composite intervals
• Assessing the impact of climate events on vegetation productivity using VIIRS-derived greenness values

Strengths

• Utilizes VIIRS sensor data for consistent 10-day monitoring intervals
• Standardized biophysical dimensionless quantity (0-1) allows for cross-regional comparison
• Produced by Copernicus, ensuring high-standard Earth observation protocols

Limitations

• Geographic restriction to the Northern Mariana Islands limits broader regional analysis
• GEOTIFF format requires specialized GIS software or libraries for data extraction
• Lack of tabular metadata makes direct statistical analysis without spatial processing difficult
