Visualization showcasing the transport of Carbon Monoxide (CO), Particulate Matter (PM 2.5), Ozone (O3) and Nitrous Oxides (NOx) during July-August 2024, which was an active fire season in Northern America. This visualization is rendered on a rotating Earth and is provided in 5760x3240 pixels (16:9 aspect ratio).

NASA utilizes satellite instruments and models to monitor sources of air pollutants and their movement through the atmosphere. This visualization shows concentrations of air pollutants, such as Particulate Matter (PM2.5, fine particles smaller than 2.5 micrometers), Ozone (O3), Carbon Monoxide (CO), and Nitrogen Oxides (NOx) as they are tracked from NASA's Goddard Earth Observing System Composition Forecasting (GEOS-CF) system. This data is used around the world to develop new methods for improving local air quality predictions, to understand the impact of pollution on human health, and to improve the quality of NASA satellite datasets.
