A global downstream approach to mapping surface urban heat islands using open data and collaborative technology
As the year winds down and temperatures (hopefully) drop for the holidays, we share a methodological contribution on the opposite problem. This paper presents an automated, open-source workflow for mapping Surface Urban Heat Island Intensity using globally available remote-sensing data, with a focus on reproducibility, scalability, and transparent downstream processing. The work was born in a grassroots climate-activism context, where the need for accessible, transferable, and openly auditable tools was central, and we welcome discussion on assumptions, limitations, and extensions within open urban climate research https://doi.org/10.1016/j.susgeo.2025.100006
