UrbanSIS
Urban SIS: Climate Information for European Cities is a project funded by Copernicus. The goal of the project is to provide a proof-of-concept of a service offering Essential Climate Variables (ECV) and impact indicators based on temperature and other climatic variables together with air pollutant concentrations. This information will bring more consistent and useful data to different sectors operating in urban areas, e.g. related to infrastructure and health. Note also that ozone and aerosols are part of the atmospheric ECVs, as defined by GCOS.
An overview of the project is given in our Urban SIS flyer.
