BOREAS 1994 Regridded NDVI Maps for Boreal Forest Analysis

Global boreal forest vegetation data from 1994, derived from 1-km FASIR-NDVI maps by Jing Chen and averaged to a 10' by 5' latitude/longitude grid. The dataset contains processed images where each pixel represents the average NDVI value, with a zero-value assignment for areas with over 50% cloud or missing data. It is maintained by ORNL_CLOUD and appears on multiple authoritative platforms.

Use Cases

• Analyzing spatial patterns of vegetation health in the 1994 boreal forest using NDVI pixel values.
• Studying long-term changes in boreal ecosystems by comparing this 1994 baseline with newer datasets.
• Validating climate and vegetation models with historical, spatially averaged NDVI observations.
• Assessing the impact of cloud cover on historical remote sensing data via the dataset's zero-value masking method.

Strengths

• Data is derived from the established 1-km FASIR-NDVI product by researcher Jing Chen.
• Appears on multiple authoritative platforms (NASA EarthData, Data.gov), indicating vetting and importance.
• Provides a specific cloud and missing data handling rule: pixels with >50% issues are assigned a value of 0.

Limitations

• Core metadata conflicts: last update date is listed as both 1995-01-01 and 2026-03-13.
• No column names, row counts, or precise file sizes are provided by any source.
• Original data resolution (1-km) has been averaged, reducing spatial detail for analysis.
