  1. Improving Air Quality Mapping by Adding NASA Satellite Data May 24, 2012

  2. Big Picture: Project Objectives Without satellite data, contouring would not be possible in the hatched areas. • Improve operational air quality maps currently in AIRNow and make them available 24 hrs a day every day • Provide satellite data products in AIRNow-Tech • Improve tools for air quality forecasting

  3. Outreach • Evaluation of the economic and societal benefits of using satellite data • AIRNow Stakeholder buy-in • Other videos, papers, conferences, etc.

  4. Socio-Economic Benefits Analysis • Applied for an augmentation to the contract • Contracting with an independent firm • Strengthen our results by adding in the $ saved, jobs created, etc. to the statistics • Literature review, detailed selection and review of areas for study, describe changes, describe benefits and impacts • Start in early January 2012 and continue through 2013.

  5. Stakeholder Buy-in • Plan for 2012: • Educate stakeholders • How 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 level • Form subcommittee of ~5 stakeholders to: • Evaluate ASDP products • Share results on monthly conference calls • Brief AIRNow Steering Committee periodically on progress • Evaluate the accuracy and usefulness of the ASDP • Incorporate EPA and stakeholder feedback during testing and development

  6. ASDP Overview Pre-processing Pre-processing Satellite Data AIRNow Obs Fusion Sat Obs Kriging Core Sites Sat Unc Obs Unc Test Sites Fusion Testing Test Extraction Stats Fused Unc Fused

  7. Preliminary Results: Smoke and No Monitors (Kansas) Observed Data Satellite Data MODIS & AIRNow Observations • Smoke in Nebraska (MODISand AOD) • No Monitors • ASDP adds information (Moderate) • Next Steps: How good is this information (scientific and socio-economic POV) Fused Data

  8. Preliminary Results: Isolated Unhealthy for Sensitive Groups Observed Data Satellite Data MODIS & AIRNow Observations • High AOD (smoke?) in central Indiana • Large USG area due to interpolation • ASDP constrains the monitor influences • Next Steps: How good is this information? (scientific and socio-economic POV) Fused Data

  9. Preliminary Results: Next Steps • Scatter plots • Spatial statistics – How much information was added with satellite data? • Statistical metrics – RMSE, standard error, etc. RMSE = root mean square error

  10. ASDP Website Linked to AIRNow-Tech user information (i.e., only the home page is currently accessible without logging in) • Project and method description • Project team roles and contact information • Experimental maps • Comments http://asdp.airnowtech.org

  11. Issues, Needs, and Next Steps • ASDP • Establish a real-time data feed • Integrate the ASDP modules into AIRNow • Determine where the algorithms will run (begin conversations with NOAA) • Socio-Economic Evaluation • Gather data needed and contract with firm to begin evaluation • Outreach • Additional videos (awaiting award from NASA)

  12. Complete testing and evaluation Establish a real time AOD data feed Finalize a software specification document Integrate the ASDP within AIRNow ops Engage AIRNow stakeholders Begin to gather data for the economic and societal impacts investigation Develop a long term operations plan Plans for Year Three - 2012
