Yemen: 10-Day VIIRS Vegetation Health and FAPAR Anomalies

Geospatial imagery of 10-day composite Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Yemen, produced by Copernicus. The data utilizes Visible Infrared Imaging Radiometer Suite (VIIRS) sensors to monitor vegetation health and detect agricultural drought impacts. Records are provided as dimensionless values ranging from 0 to 1 to indicate absorption levels.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly deviations from historical norms
• Monitoring vegetation productivity trends using the 10-day composite time series
• Assessing environmental health in Yemen by mapping the 0 to 1 absorption values across different regions

Strengths

• Utilizes 10-day time composites from the Visible Infrared Imaging Radiometer Suite (VIIRS)
• Standardized biophysical quantity (FAPAR) with values ranging from 0 to 1
• Available in GEOTIFF format for geospatial analysis

Limitations

• Metadata does not specify the total number of records or file sizes
• Geographic scope is limited to Yemen
