1Improving Air Quality Mapping by Adding NASA Satellite Data1Big Picture: Project Objectives

Improve operational air quality maps currently in AIRNow and make them available 24 hrs a day every dayProvide satellite data products in AIRNow-TechImprove tools for air quality forecasting2Without satellite data, contouring would not be possible in the hatched areas.2NO2 precursor information.OutreachEvaluation of the economic and societal benefits of using satellite data

AIRNow Stakeholder buy-in

Other videos, papers, conferences, etc.33Socio-Economic Benefits AnalysisApplied for an augmentation to the contractContracting with an independent firm Strengthen our results by adding in the $ saved, jobs created, etc. to the statisticsLiterature review, detailed selection and review of areas for study, describe changes, describe benefits and impactsStart in early January 2012 and continue through 2013.44Stakeholder Buy-inPlan for 2012:Educate stakeholdersHow does the satellite measure air quality?How are different data sources weighted? Develop fact sheet to be distributed internally and externally

Engage stakeholders from the ground levelForm subcommittee of ~5 stakeholders to:Evaluate ASDP productsShare results on monthly conference callsBrief AIRNow Steering Committee periodically on progress

Evaluate the accuracy and usefulness of the ASDPIncorporate EPA and stakeholder feedback during testing and development55ASDP OverviewTestingFusionPre-processingCore SitesTest SitesAIRNow ObsObsObsUncSatSatUncFusedFusedUncFusionKrigingPre-processingTest ExtractionSatellite DataStats66

Preliminary Results: Smoke and No Monitors (Kansas)7Smoke in Nebraska (MODIS and AOD) No MonitorsASDP adds information (Moderate) Next Steps: How good is this information (scientific and socio-economic POV)Observed DataSatellite DataFused DataMODIS & AIRNow Observations7

Preliminary Results: Isolated Unhealthy for Sensitive Groups8High AOD (smoke?) in central IndianaLarge USG area due to interpolationASDP constrains the monitor influencesNext Steps: How good is this information?

9RMSE = root mean square errorA few examples of the types of analysis we will be performing. We developed a tool for helping to create these plots quickly. We still need to do more analysis on the results.9ASDP WebsiteLinked to AIRNow-Tech user information (i.e., only the home page is currently accessible without logging in)Project and method descriptionProject team roles and contact informationExperimental mapsComments

10Issues, Needs, and Next StepsASDPEstablish a real-time data feedIntegrate the ASDP modules into AIRNowDetermine where the algorithms will run (begin conversations with NOAA)

Socio-Economic EvaluationGather data needed and contract with firm to begin evaluation

Outreach Additional videos (awaiting award from NASA)

1111Plans for Year Three - 2012Complete testing and evaluationEstablish a real time AOD data feedFinalize a software specification documentIntegrate the ASDP within AIRNow opsEngage AIRNow stakeholdersBegin to gather data for the economic and societal impacts investigationDevelop a long term operations plan1212
