Monthly maximum recomposite NDVI data for the Amazon region from August 1981 through July 1994. The dataset is derived from the NOAA/NASA Pathfinder Composite Data Set and reprojected to a 0.1-degree spatial resolution. It was produced by the SCIOPS organization.
Use Cases
- Analyze temporal trends in the monthly maximum NDVI values to study Amazonian vegetation response to climate cycles.
- Model vegetation phenology and seasonal greenness patterns across the Amazon region using the 0.1-degree gridded data.
- Validate newer satellite-derived vegetation products by comparing them with this historical Pathfinder NDVI time series.
- Assess correlations between regional NDVI anomalies and historical climate events like El Niño during the 1981-1994 period.
Strengths
- 13-year temporal coverage from 1981 to 1994

Limitations
- Data is over 30 years old, ending in July 1994
- Unknown row/column count and specific file structure
- Limited to the Amazon region, not global
