Abstract
This study provides a comprehensive dataset (FAIRUrbTemp) that addresses the lack of high-resolution urban air temperature
data across Europe. It compiles sub-hourly street-level air temperature data from 811 low-cost to commercial sensors across
several European cities and offers data in a quality-controlled, standardized format in sub-hourly, hourly, and daily resolutions.
In addition, detailed metadata, as an important source of information in urban studies, is provided at network, station, and
measurement levels. This pan-European dataset is rigorously quality-controlled using a serially automatic method applicable to
diverse city-scale air temperature data, which identifies systematic and minor inconsistencies to enhance reliability. Expertbased
validation shows that the QC reliably identifies problematic measurements, while its performance varies across urban
and climatic settings due to local environmental and instrumental effects. To ensure transparency, the results of the quality
control are provided to the user together with the original value in the dataset. The validated FAIRUrbTemp is a valuable
resource for urban climate studies, with direct applications in validating microclimate models, assessing heat-health risks, and
informing climate-adaptive urban planning.
