The second weekend of May, 15 citizens of Malgrat de Mar participated in a citizen science campaign to study the Urban Heat Island (UHI) effect, organized in collaboration with the I-CHANGE Barcelona Living Lab on Extreme Events and as part of a final degree project from the Faculty of Physics at the University of Barcelona. 

The campaign began on Friday, May 10, with an informational session where participants received training on the importance of the study and their contribution to citizen science. During this session, the functioning of Meteotrackers was explained, and assistance was provided to link these devices to mobile phones, ensuring that each participant was prepared for data collection. On Saturday, May 11, the participants cycled around the municipality, following previously assigned unique routes to cover the entire area of the municipality, taking measurements both in the morning and at night. In the two occasions, all of the participants started at the same time. This methodology allowed to covert a large part of the territory and a to obtain consistent data collection. 

The collected data will be analyzed in the coming weeks to provide a detailed view of the temperature variations in different areas of Malgrat de Mar. The final results of the study are expected to be presented at a community conference, where participants will discuss how these findings can influence urban policies and public space planning to combat the heat island effect in Malgrat de Mar.
