  1. Bullet One year data of a customisable real-time weather monitoring system at street level, with public outreach in Freiburg, Germany, Feigel, Gregor, Plein, Marvin Raphael, Zeeman, Matthias J., Metzger, Swen, Matzarakis, Andreas, Schindler, Dirk, Christen, Andreas, Conference contribution: Beating the Heat, ETH Zürich, Rising temperatures and heatwaves are increasingly threatening more lives all over the world, meanwhile also across Europe. As a result, the number of tropical nights, with air temperatures above 20°C during the night causing people to begin to suffer, has been increasing. Climate adaptation and emergency management benefit from the incorporation of real-time weather data. Placing sensors at street-level, however, is challenging: Sensors need to be small, rugged, safe, and they must measure a number of quantities within limited space. Such systems may ideally require little or no external power, provide remote accessibility, sensor interoperability and real-time data transfer and must be cost-effective for mass deployment. However, these characteristics as well as a wide spectrum of observed variables are not available in affordable commercial sensor network solutions, which is why we have designed and implemented a custom partly in-house developed two-tiered sensor system. Fifteen fully in-house developed, cost-effective “Tier-I stations” were designed and optimised from scratch to enable a stable real-time Weather-Sensor-Network (WSN) that supports a wide range of sensors, also being easily expandable. They provide data on wind, radiation, pressure, lightning, solar radiation and black globe temperature. To better resolve spatiotemporal weather patterns such as urban heat islands, 35 commercial off-the-shelf sensors increase the spatial density of air temperature, humidity and precipitation observations and expand the observed domain. Both sensor systems are integrated into a comprehensive data management infrastructure, which allows for a real-time quality control and remote management. Furthermore, our in-house developed uniWeather app offers stakeholders and the public access to real-time data and its interpretation. Dissemination plays not only a crucial role in science communication, but is also paramount for adaption to climate change such as heat waves. Since the deployment in summer 2022, our stations have collected high-resolution data (60 sec) continuously for a period of one year with minimal data loss, providing a substantial dataset. Results of spatiotemporal heat stress patterns in Freiburg will be discussed which underline the importance of urban planning with regard to minimising the negative aspects of the urban heat island effect. https://zenodo.org/records/8367147, 2023.
