Urban areas often suffer from poor air quality, leading to higher levels of asthma, heart disease, and premature death. Most global cities have no ground-based monitors to provide key health and environmental information, and monitors are limited even in the U.S.  Satellite data offers a powerful new tool to “see” air pollution from space, even gases that are invisible to the human eye. Tracey Holloway has helps lead a NASA science team to connect satellite data with air quality planning. These data can support energy policies, health assessment, and the design of livable cities.
