Enhancing Air Quality Mapping with NASA Satellite Data: Project Overview and Objectives

This project aims to improve operational air quality maps in AIRNow by integrating NASA satellite data, making these maps available 24/7. Key objectives include providing satellite data products, enhancing forecasting tools, and evaluating the socio-economic benefits of satellite data usage. A stakeholder engagement plan will educate and involve stakeholders throughout the process, assessing the accuracy and usefulness of the data. The project began in January 2012 and will continue through 2013, focusing on real-time data integration and comprehensive impact analysis.

  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
