    Slide 1:Remote Operation of a Modern PM and Trace-Gas Monitoring Network

    Prepared by: Joey Landreneau, David Vaughn, Paul Roberts Sonoma Technology, Inc. Petaluma, CA Presented at the National Air Quality Conference Dallas, TX March 5, 2009 3551

    Slide 2:Presentation Outline

    EPA and NCore requirements, recommendations Example installations Monitoring sites with Ethernet connectivity Monitoring sites with wireless internet What’s next? Evaluate your monitoring network communications system

    Slide 3:Revised Ambient Air Monitoring Regulations

    In September 2006, EPA revised Ambient Air Monitoring regulations Purpose: to help the EPA, S/L/T improve public health protection and better inform the public about air quality in their communities AQ regulators should take advantage of improvements in monitoring technologies New multi-pollutant sites (NCore) More real-time AQ measurements for particle pollution and ground-level ozone

    Slide 4:Monitoring Plan: July 01, 2009 Operational: January 01, 2011 PM2.5 measurements: Continuous FEM & FRM PM2.5 mass, PM2.5 speciation PM10-2.5 mass and speciation Continuous precursor measurements: O3; trace-level SO2, CO, NO/NOY Waivers may permit NOX to replace NOY Meteorological parameters: WS, WD, RH, TEMP Met requirements can be waived Report (hourly) data to AIRNow-Tech and all data to AQS

    NCore Requirements

    Slide 5:Digital over analog for recording analyzer readings and diagnostic information No more phone lines Primary telemetry – high-speed Ethernet service Secondary telemetry – wireless internet service Proprietary software in modern monitors requires high-speed connectivity

    NCore Recommendations Reference: Data Acquisition Consideration in the NCore Monitoring Program By Nealson Watkins and Lewis Weinstock U.S. EPA, Office of Air Quality Planning and Standards Precursor Training Workshop November 2006

    Slide 6:Example Solution: Ethernet Connectivity (1 of 6)

    6-station network with Ethernet connectivity Serial interface NOx, CO, Dilution calibrator, BC, Nephelometer Analog interface WS, WD, Temp at two heights, RH, solar radiation, pressure Particulate PAH (polycyclic aromatic hydrocarbons) Near real-time data viewing via website Graphic display of all continuous data 5-minute data updated every 10 minutes

    Slide 12:4-station network with wireless internet connectivity Serial interface NOx, NMHC, CO, Dilution calibrator, BC, Nephelometer Analog interface WS, WD, Temp at two heights, RH, solar radiation, BP Particulate PAH (polycyclic aromatic hydrocarbons) Near real-time data viewing via website Graphic display of all continuous data 5-minute data updated every 10 minutes

    Example Solution: Wireless Internet (1 of 5)

    Slide 13:Wireless Internet Solution (2 of 5)

    Virtual Network Computing (VNC) application Proxicast LAN-CEL-2, 3G Cellular Router Linksys WET54G Wireless-G Ethernet bridge 6db Yagi Antennas

    Slide 14:Wireless Rack Configuration (3 of 5)

    Slide 15:Wireless Internet Solution (4 of 5)

    Slide 16:Wireless Internet Solution (5 of 5)

    Slide 17:Wireless Figures Prominently in AQ Monitoring Today

    Ambient air monitors with serial interfaces are IP enabled Wireless IP networks and internet distribution and dissemination of digital data are practical and reliable No constraints from communication cables Affordable implementation and operation of wireless digital telemetry

    Slide 18:What’s Next?

    Evaluate your AQ monitoring network communications system Does your system comply with revised monitoring regulations? Does the system need to be upgraded regardless of new regulations? Where are improvements warranted? Does your system comply with revised monitoring regulations to take advantage of real-time monitoring advances and thus to allow better distribution of the data to the public? What is the maintenance and repair status of the current system? Does the system need to be upgraded regardless of new regulations? Where are improvements warranted?Does your system comply with revised monitoring regulations to take advantage of real-time monitoring advances and thus to allow better distribution of the data to the public? What is the maintenance and repair status of the current system? Does the system need to be upgraded regardless of new regulations? Where are improvements warranted?
