Monitoring was undertaken as part of the ‘Cardiff Urban Geo-Observatory’ project. Boreholes are located within the urban area of the City of Cardiff, Wales, UK. The majority of temperature sensors were installed within boreholes that monitor a shallow Quaternary aged sand and gravel aquifer, however the made ground and the Triassic Mercia Mudstone also represented. Temperature sensors installed in 54 boreholes, between depths of 1.5m and 18.9 m below ground, with measurements every 30 minutes. The dataset comprises of just over 3.5 million temperature measurements. Monitoring was undertaken by the British Geological Survey and was designed to address knowledge gaps of subsurface Urban Heat Island and its use for heat recovery and storage.

Sensors included; Hobo® ProV2 with a resolution of 0.02°C and an accuracy of ±0.21°C and Solinst Levellggers with a resolution of 0.003°C and an accuracy of ± 0.5°C. Since 2018 the network has been harmonised and the majority of boreholes are now instrumented with Solinst Levelloggers, that measure both water pressure and temperature. Groundwater temperatures were measured every 30 minutes between 2018 to 2024. Data from the instruments was collected manually every year and was ingested into the BGS corporate database for sensor data before being extracted into the CSV format provided in this dataset.
