Rainfall Data from Acoustic Sensors in Zurich and Milan, Spring-Summer 2022

Zurich, Switzerland and Milan, Italy are the locations for this rainfall dataset. It contains information from acoustic sensors and rain gauges, with data collected at 15-minute intervals for Zurich in April 2022 and at 1-minute intervals for five rain events in Milan in June 2022. The dataset was created by Nadav Peleg of the University of Lausanne and is associated with a scientific publication.

Use Cases

• Compare acoustic sensor rainfall detection against traditional rain gauge measurements based on the parallel data collection described.
• Analyze rainfall intensity and drop count patterns for specific urban events based on the high-frequency 1-minute data for Milan.
• Study seasonal rainfall characteristics in spring and summer based on the temporal coverage in Zurich and Milan.
• Validate sensor network performance for urban climate monitoring based on the described sensor metadata and preliminary quality control.

Strengths

• Includes data from two distinct European cities, Zurich and Milan, allowing for comparative analysis.
• Provides high-temporal-resolution data, with 1-minute intervals for Milan and 15-minute intervals for Zurich.
• Combines measurements from two sensor types: acoustic sensors (rain drop counts) and traditional rain gauges (rainfall depth in mm).
• Associated metadata files detail the locations of the acoustic sensors and rain gauges.

Limitations

• The data has only passed preliminary quality control, which may affect its reliability for certain applications.
• The temporal coverage is limited to specific months in 2022 (April for Zurich, June for Milan), not a full year.
• Column-level documentation is absent; field semantics must be inferred after download.
