This Web site serves the OTAG Air Quality Analysis working group. OTAG is a partnership between the EPA, the Environmental Council of the States, ECOS and other stakeholders to develop a thoughtful assessment and a consensus agreement for reducing regional background ozone and its precursors, explicitly addressing inter-regional ozone transport over the Eastern US.
Thoughtful assessment is supported by policy-relevant data from AIRS and other sources. The data analysis for assessment is distributed over a diverse group of participants but the data used, the processing tools and the results are shared through the links on this Web site. Critical evaluation and consensus-building is encouraged by interactive annotation facilities for feedback and comments on specific facts or general issues.
