Short Summary

This dataset provides laboratory calibration results for tipping-bucket rain gauges using both automated and manual burette methods across five rainfall intensities, enabling comparison of calibration performance and serving as a benchmark.

Objective

• To provide a comprehensive laboratory calibration dataset for tipping-bucket rain gauges, facilitating the comparison of automated and manual calibration methods and establishing a benchmark reference.

Study Configuration

• Spatial Scale: Laboratory setting
• Temporal Scale: Experiments conducted across five rainfall intensity levels (10 mm/h, 20 mm/h, 30 mm/h, 50 mm/h, and 100 mm/h), with a fixed target total rainfall of 20 mm for each trial, and 15 repeated trials per condition.

Methodology and Data

• Models used: Guide to the Expression of Uncertainty in Measurement (GUM) for uncertainty estimation (including Type A, Type B, combined, and expanded uncertainty).
• Data sources: Laboratory experimental data from tipping-bucket rain gauge calibrations using an automated system (PRC-20AP) and a conventional manual burette-based method.

Main Results

• The dataset contains raw data, summary statistics, and automated analysis worksheets for calibration performance metrics including total rainfall, rainfall intensity, relative error, repeatability, and uncertainty for both automated and manual calibration methods across five rainfall intensity levels.

Contributions

• Provides a unique, controlled laboratory calibration dataset for tipping-bucket rain gauges, serving as a benchmark for future calibrations and enabling direct comparison of automated and conventional manual calibration methodologies.
