AVHRR: Global Land 10-Day Vegetation Index Composites at 1-km Resolution

A time series of global 10-day normalized difference vegetation index composites derived from daily AVHRR observations. The data is a component of NASA's AVHRR Pathfinder Program, produced through a collaboration involving NOAA, NASA, USGS, ESA, CSIRO, and 30 international ground stations. The time series begins in April 1992 and continues for specific time periods.

Use Cases

• Monitor global vegetation health and phenology based on the 10-day normalized difference vegetation index composites.
• Analyze long-term land surface changes based on the time series beginning in 1992.
• Model climate-vegetation interactions based on the 1-km resolution global land surface data.
• Calibrate and validate other remote sensing products based on the radiometrically and atmospherically corrected AVHRR observations.

Strengths

• Data is derived from daily observations that have been radiometrically calibrated, atmospherically corrected, and geometrically corrected.
• Project represents an international collaboration between multiple major space and scientific agencies.
• Time series provides a long-term record starting in April 1992.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The time series continues for 'specific time periods'; exact temporal coverage is not detailed.
