BOREAS HYD-09: Radar Rainfall Maps for Southern Study Area

BOREAS HYD-09 radar data focuses on a 100-km range to eliminate less accurate precipitation estimates. This dataset provides Cartesian maps of rain accumulation for 1-hour and daily periods over the Southern Study Area during summer 1994. A parallel set of 1-hour maps for the full radar view is available upon request from the HYD-09 team.

Use Cases

• Modeling forest water budgets based on high-temporal-resolution (1-hour) radar rainfall estimates.
• Validating satellite-derived precipitation products using ground-referenced radar data from the SSA.
• Analyzing summer storm patterns in 1994 using daily rain accumulation maps.
• Studying radar rainfall accuracy degradation beyond a 100-km range as noted in the data collection methodology.

Strengths

• Data is focused within a 100-km radar range, a deliberate selection to eliminate less accurate estimates.
• Provides precipitation data at two temporal resolutions: 1-hour and daily periods.
• Dataset is hosted by the National Aeronautics and Space Administration, indicating institutional provenance.

Limitations

• Conflicting metadata: 'last updated' dates conflict between 1994-09-23 (nasa_earthdata) and 2026-03-13 (datagov).
• Sparse column information; specific data variables and map dimensions are not detailed.
• Spatial coverage is limited to the Southern Study Area (SSA), not the full radar view or Northern Study Area (NSA).
