3. Main Messages Satellite imagery has changed our understanding of air pollution as a global problem. Air pollution sources globally, and their influence domestically, are expected to grow unless new policies are implemented. Observations from satellites (and associated global models and information systems) are important tools to help: – Understand and account for global influences on U.S. air quality. – Motivate and enable emission reductions of sources of air pollution in other countries It is in the U.S. national interest to – promote public awareness, technical capacity, and access to information about air pollution and air quality management globally – encourage the integration of air quality objectives into sustainable development efforts around the world.

Monitoring of the global distributions of greenhouse gases, reactive gases and aerosols through assimilation of satellite and in situ observations, using near real time, delayed-mode, and reanalysis production systems (including NASA and EPA observations). Twice-daily forecasts of the global distributions of reactive gases and aerosols for several days ahead. An ensemble of three data assimilation systems for stratospheric ozone and a long- term reanalysis of total column ozone. Boundary values for regional modelling of tropospheric and stratospheric chemistry, and local and urban modelling for air quality. Global fire analyses and estimates of emissions from fires for use in the global and European regional monitoring and forecasting systems; Surface fluxes of carbon dioxide, methane and aerosols produced using inverse methods; Global datasets for emissions from sources other than fires, to be updated based on new statistics or results from flux inversion.

24. Questions for Discussion Does the U.S. need a “CAMS-like” operational system to support air quality research and management? – What CAMS functions are not supported by programs in the US? – Can these functions be fulfilled by an Applied Science Team approach? How would a U.S. service-oriented system differ from CAMS? What can be leveraged from CAMS? What can be learned? What would be the roles of different federal and state agencies? What institutional changes or innovations are needed? How will geostationary satellites (e.g. TEMPO) change the needs and opportunities? In general, how do we better facilitate the transfer of knowledge and methods from NASA/NOAA/NSF research activities to NOAA/EPA/State operations and applications?
