Thanks to a new citizen science initiative called xAire, 810 new air-quality sensors will be installed throughout Barcelona starting this Friday. This dramatic expansion of the local sensor network—currently comprising just seven permanent sensors—will allow more detailed mapping of the nitrogen dioxide (NO2) content in the city’s air. The oxidizing properties of NO2, a gas produced primarily by diesel-powered motor vehicles, make it extremely harmful to health.
xAire is an intergenerational citizen science project that follows in the footsteps of London’s Mapping for Change initiative. The new project is being coordinated by Estació Ciutat—the environmental health clinic of the Centre for Contemporary Culture of Barcelona (CCCB)—and sponsored by DKV and 4sfera Innova. xAire’s collaborators include ISGlobal, Mobile Week Barcelona, Mapping for Change, OpenSystems (University of Barcelona), and the Barcelona Education Consortium’s 5th Science Congress.
“This is an innovative opportunity to work more collectively on one of Barcelona’s biggest public health problems,” commented Carolyn Daher, Coordinator of the Urban Planning, Environment and Health Initiative at ISGlobal. With the highest density of vehicles in Europe, Barcelona has repeatedly failed to meet air-quality guidelines set by the European Union.
