This dataset includes minute-interval rainfall for the years 1961, 1965, and 1998-2024, and daily rainfall for the periods 1965-1966 and 2007-2024.
Before 2006, rainfall was measured using a siphon rain gauge with a measurement range of 0.1 mm to 10 mm and an error margin of ±0.05 mm. This gauge could measure precipitation intensities from 0.1 mm/10 min to 40 mm/10 min. From 2006 to 2023, rainfall measurements were conducted using a tipping-bucket rain gauge, which had a range of 0-4 mm/min, a minimum measurement increment of 0.1 mm, and a maximum allowable error of ±4%. In 2024, the rainfall was monitored by piezoelectric rain gauges , which had a range of 0-200 mm/h, a minimum measurement increment of 0.1 mm, and a maximum allowable error of ±4%. Before 2024, the rainfall data are stored in a logger system that records rainfall time. Every 3 months, data are retrieved from the logger, the rain gauge is cleaned if needed (leaves, spider web). The 2024 rainfall data measured by piezoelectric rain gauge was transmitted wirelessly via 4G signals. With a dome-type sensor area, this new type of rain gauge requires no maintenance.
The minute rainfall data is the original data, and the daily rainfall data is obtained by summing up the minute rainfall data.
The data quality is reliable.
