3. 3 Introduction Since its inception over 10 years ago, AIRNow has evolved continuously. Over the past year, several changes have occurred. An overhaul of the system architecture including new mapping and data software A new layout for AIRNow.gov Several new web services EnviroFlash upgrades

4. AIRNow Migration Overhauled system architecture New SQL database New software programs for the management of real-time and historical air quality data – Data Management System (DMS): ingest, quality control, and validate real-time air quality data – Information Management System (IMS): generate maps and files, exchange data through web services 4

5. New AIRNow Maps Forecasts: Observations: Interpolated maps of air quality forecasts and observations at national, regional, and local scales Maps update automatically as new data or forecasts are received 5

6. AIRNow.gov Changes Easier navigation to local air quality conditions and forecasts Improved air quality maps— forecasts, observations, and animations old website new website 6
