Da-Tun Mountain Rainfall at Minute Resolution, 2009–2023

High-resolution precipitation observations from a network of 25 automatic rain gauges in the Da-Tun Mountain region of northern Taiwan. The dataset provides continuous 1-minute rainfall measurements from June 2009 to December 2023, with derived 10-minute, hourly, daily, and monthly products. It was created by Lin-Wen Cheng and accompanies a Scientific Data manuscript.

Use Cases

• Analyzing extreme rainfall events and precipitation enhancement based on high-density, minute-resolution station data.
• Modeling hydrological processes in mountainous terrain based on long-term, quality-controlled rainfall records.
• Studying orographic effects on precipitation under typhoon conditions based on multi-station observations.
• Validating satellite or radar precipitation estimates based on ground-truth measurements from a dense gauge network.

Strengths

• Provides 1-minute resolution rainfall data, a high temporal detail for meteorological research.
• Covers a 14.5-year period from June 2009 to December 2023, offering a long-term record.
• Includes data from 25 rain gauges, suggesting a dense spatial network for the study area.
• Features a multi-stage quality-control procedure and clearly flags missing values.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
