  1. Webinar: AIR Now and Air Quality System (AQS)July 13, 2011

  2. Agenda • Introductions • Sarah Swenson, EPA (facilitator) • John E. White, EPA (presenter) • Format • EPA speaker (15 minutes) – overview of Air datasets • Lines are muted - submit questions as the speakers talk • Questions and Answers (15 minutes) • See the website: epa.gov/appsfortheenvironment

  3. Background about the Challenge • Apps must use EPA data and address one of EPA Administrator Lisa Jackson’s Seven Priorities • Judged based on usefulness, innovativeness, and usability • Submissions are due by September 16 • Winners and runners up for Best Overall App and Best Student App, plus People’s Choice • Recognition from EPA in Washington, D.C. in November • Get more details at epa.gov/appsfortheenvironment

  4. AIRNow Web ServicesOverview of Available Data Prepared by Steven A. Ludewig, Timothy S. Dye Sonoma Technology, Inc. Petaluma, CA John E. White U.S. Environmental Protection Agency Research Triangle Park, NC 3800

  5. AIRNow Program Overview • AIRNow is the National system for acquiring and distributing air quality observations and forecasts to the public • Voluntary participation • 130 federal, state, local, and tribal air quality agencies) • Standardized Air Quality Index (AQI) • Partnerships with national media • Air quality education and outreach • Emergency response (e.g., wildfires) • Exceptional Event tools • EnviroFlash

  6. The Air Quality Index

  7. AIRNow Web Services: Why Are They Needed? • Web Services provide a way to retrieve data and information ‘on demand’ from the AIRNow system. • Forecasts • Action days • Observed data • Multiple format options including maps • Agency, reporting area, and monitoring site information • Uses • Agency websites, web developer access • Local news organizations • Other agencies • Schools and researchers • Spreadsheets and other applications • The public

  8. AIRNow Web Services A few potential uses

  9. AIRNow Web Services • Where we’ve been • Simple Object Access Protocol (SOAP): not as simple or clean as it sounds • Progress in 2009 • A RESTful approach • The future – an AIRNow Application Programming Interface (API) • Additional services, data sets, and formats useful for building applications • An easier to use, well-documented interface

  10. AIRNow Web Services: A RESTfulApproach • Example question: “What is the current air quality forecast for my home town ZIP Code?” • URL:http://ws.airnowgateway.org/GatewayWebService REST/Gateway.svc/forecastbyzipcode?key=43321E-F56Q-B612-68FBN&zipcode=95401&format=csv • Looks complicated, but let’s break it down • ForecastByZIPCode = the name of this request* • Key = unique user key • ZIPCode = ZIP Code of interest • Format = payload options (CSV, JSON, KML, XML, etc.) • Optional: Date = any date of interest (defaults to the current date) *a companion service exists for observed data: ObservedByZIPCode

  11. AIRNow Web Services (example) Use of ForecastByZIPCode and ObservedByZIPCode services by the EPA MyEnvironment website: www.epa.gov/myenvironmentand other state web sites

  12. AIRNow Web Services Use of a geospatial Web Coverage Service (WCS) by Shasta County, CA: http://www.co.shasta.ca.us/html/ResMgmt/AQ/aq_map.aspx KML file
