Guyana FAPAR Vegetation Index Anomalies: 10-Day VIIRS Composites

Copernicus provides 10-day time composite geospatial data of Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) anomalies for Guyana. Derived from the Visible Infrared Imaging Radiometer Suite (VIIRS), these GEOTIFF files measure vegetation health and greenness on a scale of 0 to 1. The dataset was last updated in March 2026 to support agricultural drought monitoring and productivity assessment.

Use Cases

• Detecting agricultural drought by analyzing FAPAR anomaly values across different 10-day composites
• Monitoring vegetation health trends in Guyana using the 0 to 1 dimensionless absorption scale
• Assessing crop productivity impacts by correlating GEOTIFF spatial data with known agricultural zones

Strengths

• High temporal resolution with 10-day time composites
• Standardized 0-1 dimensionless scale for biophysical absorption
• Derived from Visible Infrared Imaging Radiometer Suite (VIIRS) sensor data

Limitations

• Geographic scope is restricted to Guyana
• Lack of accompanying tabular metadata for specific pixel-level attributes
• Potential for cloud cover interference in optical sensor readings
