Shown are PBL SO2 data from the operational algorithm optimized for observations of anthropogenic pollution in the Planetary Boundary Layer (PBL, typically below 2km). The combination of spatial smoothing and local bias correction can be used to produce these high-resolution, long-term mean SO2 maps. Significance: The maps were generated for two 3-year intervals, 2005-2007 and 2008-2010. A 24 km averaging-radius was used to smooth the data for these maps. A substantial decline in OMI SO2 values at major sources between the two time intervals is evident from the figure. This reduction is attributed to the installation of additional flue-gas desulfurization units (or “scrubbers”) at many US power plants over this period (e.g., http://www.epa.gov/airmarkets/images/CoalControls.pdf ) to meet stricter emissions limits introduced by the Clean Air Interstate Rule. Relevance for future science and relationship to Decadal Survey: Aura OMI will continue monitoring volcanic and anthropogenic SO2 from space to detect trends in volcanic and anthropogenic aerosol precursors to provide an overlap with ESA Sentinel-5 precursor mission (TropOMI) planned to launch in 2014. Decadal Survey recommended the Geostationary Coastal and Air Pollution Events (GEO-CAPE) tier 2 mission is planned to launch after 2020. It will allow more frequent monitoring of anthropogenic SO2 pollution over N America. A next generation, OMI-like sensor is being considered by the Canadian Space Agency for inclusion on the Polar Communication and Weather (PCW) mission scheduled for launch in 2017. It would monitor SO2 pollution over the Arctic and sub-Arctic regions. IMAGE #2

NASA AQAST: Serving the Needs of US Air Quality Management   The NASA Air Quality Applied Sciences Team (AQAST) was created in 2011 by the NASA Applied Sciences Program to serve the needs of US air quality management through the use of Earth Science satellite data, suborbital data, and models.  AQAST members have expertise in the wide array of Earth Science tools and data sets available from NASA and other agencies. They have the resources to carry out quick-turnaround projects responding to urgent and evolving needs of air quality management. The advantage of satellite data for monitoring changes in air pollutants is shown by nitrogen dioxide (NO2) and sulfur dioxide (SO2) data from the Ozone Monitoring Instrument (OMI), onboard the Earth Observing Satellite Aura (http://aura.gsfc.nasa.gov/). NO2 and SO2 decreased significantly from 2005 to 2011 (See maps A. & B. at left.) as a result of federal and state efforts to decrease NOx and SO2 emissions. NO2 is regulated as it is unhealthy to breathe and also reacts with other gases to produce high levels of ozone, which is dangerous to breathe. SO2 is regulated as it is unhealthy to breathe and it contributes to acid rain. More information about AQAST and its activities is available at http://acmg.seas.harvard.edu/aqast/.

The intensity of city lights (C.), measured by the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS), is an excellent indicator of the sources of pollution. The brightest lights coincide with the most urbanized, populated, and, consequently, polluted areas in the U.S. More information about AQAST and its activities is available at http://acmg.seas.harvard.edu/aqast/.
