Iran Vegetation Index Anomaly: 10-Day FAPAR Composites from VIIRS

Supplying 10-day composite Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Iran, produced by Copernicus using VIIRS sensor data. The records track vegetation health and greenness to monitor agricultural drought impacts across the country. The data is delivered as geospatial rasters updated through March 2026.

Use Cases

• Detecting agricultural drought by identifying negative FAPAR anomaly deviations
• Monitoring vegetation productivity trends using the 0-1 absorption scale
• Analyzing seasonal crop health cycles via 10-day composite time-series

Strengths

• Uses VIIRS (Visible Infrared Imaging Radiometer Suite) sensor data
• Standardized biophysical scale ranging from 0 to 1
• High-frequency 10-day temporal resolution

Limitations

• GeoTIFF format requires specialized GIS software for interpretation
• Optical sensor data is subject to interference from persistent cloud cover
• Lack of tabular metadata for specific pixel-level attributes
