Air Drifts revisits trans-boundary air pollution to analyze how localized toxic particulates drift into new territories of global responsibility. Emissions from urban and industrial activities result in black carbon, sulfates, nitrogen dioxide, ozone, dust and other particulates. These aerosols migrate extreme distances, impacting cloud formation, weather and climate. The actions of minute pollutants at massive spatial and temporal scales are almost impossible to perceive. Air Drifts collaborates with NASA to explore their “GEOS-5 Nature Run” high-resolution supercomputer model that “mirrors” the earth systems and simulates pollutant flows. This model accumulates 5 million data points every 6 hours combining ground observations and satellite monitoring to reconstruct the earth’s atmosphere at a given time. The model is used to tracks pollutants as they enter different national spaces, regimes and regulatory systems, and to visualize the air space with spectacular animations using spectral data and seamless globes. Through interviews with scientists, Air Drifts asks about the monitoring, modeling and representation of pollutants. Reinterpreting provocative scientific and visual materials, the project explores national air space, global commons, international diplomacy and the state of the atmosphere and its futures.
