RT journal article T1 Simplifying the process to perform air temperature and UHI measurements at large scales: Design of a new APP and low-cost Arduino device A1 Romero Rodríguez, Laura A1 Sánchez Ramos, José A1 Álvarez Domínguez, Servando A2 Máquinas y Motores Térmicos K1 Arduino K1 Environmental monitoring K1 GIS K1 UHI K1 Urban climate K1 Urban temperatures AB The main purpose of Urban Heat Island (UHI) studies and the monitoring of ambient temperatures at large scales is to gather temperature information in a certain area, so as to understand temperature heterogeneity and its drivers or detect locations that lack thermal comfort. However, these studies originate mostly from some research projects, with sufficient budget and manpower to carry out the measurements and the necessary calculations. Thus, there is a scarcity of air temperature information, making it difficult to implement appropriate mitigation actions worldwide. The present work aims to greatly simplify the process to monitor air temperatures and carry out UHI estimations through mobile transects. This is done by introducing the design of a low-cost device and a new APP, which performs automatically most necessary UHI calculations. A web tool based on the Inverse Distance Weighting interpolation method is also included to obtain heat maps. The methodology is illustrated using case studies in Seville (Spain) and New York city (USA). By introducing a straightforward and reproducible methodology, we aim to open the path for a more widespread availability of ambient temperature data anywhere in the world, without the need for costly equipment and many hours of dedication by the researchers PB Elsevier SN 2210-6707 YR 2023 FD 2023-04-23 LK http://hdl.handle.net/10498/28818 UL http://hdl.handle.net/10498/28818 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 22-sep-2026
