Today was another unusually hot day in Freiburg, with temperatures above 38°C. Our urban weather station network operated by @uni-freiburg.de and funded by @erc.europa.eu reveals intra-urban differences and where it was coolest (in a forest). Explore the map weather.uni-freiburg.de/map/freiburg...

During the current #UKHeatWave we measured for the first time a #TropicalNight across our Bristol street-level weather network. Stations outside the city and on hills cooled down to < 20°C while the urban heat island kept the city core above 20°C last night. weather.uni-freiburg.de/map/bristol/...

Stations colored in red show a tropical night, i.e. that air temperature at those weather stations did no drop below 20°C all night on Jun 21, 2025.

New weather stations on lamp-posts across Bristol, UK reveal interacting urban, orographic and coastal effects in real time. Last night, we observed an urban heat island of 5ºC. Multi-institutional effort between urbisphere ‪@erc.europa.eu‬, @urbanair.bsky.social‬ and ASSURE: doi.org/10.5281/zeno...

The city centre of Bristol has the highest nocturnal air temperatures measures, 5K warmer than a rural site to the west of the city at same elevation. Note also that the station in the NW near the coast stays even warmer (12.2ºC), while the Avon Gorge is relatively cool (8.8ºC).

A weather station on a lamp-post measures at 3 m in a typical street canyon, here in the Windmill Hill neighborhood. Data are transmitted every 5 minutes over the cell-phone network and shared as open-data as part of several UK and EU research projects enhancing urban-scale weather and climate modelling.

Using high-resolution weather models and a network of 25 LiDAR-ceilometers over Berlin, Germany, we explore how large cities modify the atmospheric boundary layer. New preprint on collaborative work by @uniofreading.bsky.social‬, @metoffice.bsky.social‬ and @uni-freiburg.de

Modular approach to near-time data management for multi-city atmospheric environmental observation campaigns

Abstract. Urban observation networks are becoming denser, more diverse, and more mobile, while being required to provide results in near time. The Synergy Grant “urbisphere” funded by the European Res...
