Smr Fastnet Presentation Take2 Pubs Smr Fastnet Presentation Take2 Pubs Presentation Transcript

  • The FASTNET Project Presented by: Sean Raffuse 1 Rudy Husar 2 Rich Poirot and Gary Kleiman 3 1 Sonoma Technology, Inc. 2 Center for Air Pollution Impact and Trend Analysis (CAPITA) 3 NESCAUM Presented at: U.S. EPA 2005 National Air Quality Conference San Francisco, CA February 13-16, 2005 STI-2646
  • FASTNET
    • F ast A erosol S ensing T ools for N atural E vent T racking
    • Brings together real-time and historical data sets useful for aerosol analysis into several web based consoles
    • Developed by the Center for Air Pollution Impact and Trend Analysis (CAPITA) and Sonoma Technology, Inc. (STI)
    • A Regional Planning Organization (RPO) project
    • Managed for MANE-VU by Northeast States for Coordinated Air Use Management (NESCAUM)
    • Currently functional and freely accessible
  • On Aerosol Events and Data
    • Aerosol episodes are often complex
      • Different components, shapes, sizes, mixing
      • Natural and anthropogenic sources
      • Transport and carryover
    • Aerosol data sets come from a variety of sources and are difficult to use
      • Data sets are large, many different formats and cumbersome
      • Stored and maintained at various locations
      • Dynamic
      • Represent different time/space scales
    • Aerosol data need to be integrated and presented in real time
      • Individual data sets can only provide narrow views of aerosol events
      • Data integration provides a broader characterization of events
      • Synthesizing datasets helps better understanding aerosol events
  • FASTNET is one of many projects within DataFed.net which share common data sets which are archived and accessible and can be viewed, compared, exported, analyzed, and interpreted using a variety of web-based applications FASTNET uses the DataFed.net infrastructure Supported by NSF, NASA, EPA and other Agencies
  • DataFed Synthesizes Data for Analyses Image Files Ambient Monitors Emission Inventories Fire Locations Meteorology GIS Maps Satellite Imagery Data Data Retrieval Service Outputs Websites Maps Graphs XML CSV Analyst Consoles Custom Consoles Manager Console Connects to various data types And creates standard data views Which can be incorporated into websites Databases
  • AIRNow and FASTNET The AIRNow PM 2.5 data set is the benchmark parameter used in FASTNET The products of FASTNET have the potential to be returned to AIRNow to provide context Hourly PM 2.5 data Tools and the analyst community Event analysis, packaging, and context
  • Real-time Real-time Real-time
  • Data catalog(s) provide access to many fast (rapidly available), current (near-real-time, recently archived and continuing), and slow (historical data like IMPROVE Aerosol and ATAD trajectories)
  • Event Analysis – February 19, 2004
    • Areas of elevated PM 2.5 in the Great Lakes (MN, MI), Northeast, and West Texas
    • What are the features?
  • This is one of several Analyst Consoles Visibility Meteorological parameters Satellite indices Fires Aerosol models Imagery
    • Isolated high PM 2.5 occurs over the Midwest, Northeast and Texas
    • Aerosol patches are evident in AIRNOW PM 2.5 , ASOS & FBext maps
    • The high surface wind speed over Texas, hints on possible dust storm activity
    • The NAAPS model shows high sulfate over the Great Lakes, but no biomass smoke
    February 19, 2004: Texas Dust & Midwest Nitrate Possible causes: nitrate in the Upper Midwest, sulfate around the Great Lakes, dust over Texas
  • High winds in northeast Texas and Oklahoma Navy Aerosol Analysis and Prediction System (NAAPS) Model shows dust in this area
  • Air Quality Manager’s Console Browse a subset of the FASTNET data in time and space with a simple GIS interface Hourly PM 2.5 Visibility Fire Locations GIS Data Layers
  • Event Tracker provides pre-selected views and links to other information Analyst summaries
  • Satellite images News stories
  • FASTNET Status
    • FASTNET is still under development, but available at www.datafed.net
    • Air Quality Manager’s Console at fastnet.sonomatechdata.com
    • If you are interested in participating, contact Rich Poirot (rich.poirot@anr.state.vt.us)
    • For technical information on DataFed and FASTNET contact Rudy Husar (rhusar@me.wustl.edu)
    • For information on the Air Quality Manager’s Console contact Sean Raffuse (sraffuse@sonomatech.com)

    • Other FASTNET Reports and Presentations
    • PM Event Detection from Time Series
    • Automated Detection of Regional Haze Events
    • Mystery Winter Haze over the Midwest
    • February 19, 2004 Texas-Mexico Dust Event
    • February 19 2004 PM Event over the Northeast and Quebec
    • June 4 2004 Tucson Dust
    • July 4 2004 Aerosol Pulse
    • April 28, 2004 Nevada Dust
  • Sulfate in the Northeast Sahara Dust in the Gulf Fires in the Southeast Time Series Console: Southeast Analyst Console Applications: Sulfate Episode: 8/27/04
  • A Peek Under the Hood
    • FASTNET uses the DataFed.net infrastructure
  • Relevance
    • Aerosol episodes are often complex
      • Different components, shapes, sizes, mixing
      • Natural and anthropogenic sources
      • Transport and carryover
    • Individual data sets can provide clues about the cause and nature of aerosol events
    • Synthesizing the data helps us better understand aerosol events
  • Satellite detects fires in the Southeast But PM 2.5 values are small
  • The NAAPS model suggests the high PM 2.5 in the Northeast is due to sulfate
  • Users can customize views by layering the many available data sets These custom views can be incorporated into their own websites
