The GEO Health Community of Practice (CoP)’s Air Quality, Wildfires, and Respiratory Health Work Group aims to identify and disseminate recent progress in air quality applications of Earth observations (EO) to advance respiratory health management and decision-making as it is impacted by air quality. These EO applications include forecasting and early warning for poor air quality, observations of air quality and its drivers using satellite remote sensing, and investigations of the impacts of air quality on human, animal, and ecosystem health through combinations of EO with other environmental data. The activities of this work group support the One Health approach by recognizing that air quality issues represent a key intersection of human, animal, and environmental health.
