Title: Air Quality System AQS Status and Plans


1
Air Quality System (AQS) Status and Plans
  • Part 1 Nick Mangus
  • US EPA
  • Boring Infrastructure Stuff
  • Part 2 Mike Matsko
  • NJDEP (Representing AQDE Team)
  • Interesting Implementation Projects

2
Topics for Part 1 Status Plans
  • AQS and AirNow Background
  • Similar Data
  • Separate flows
  • Flow Status
  • Node Flow
  • New Version of Schema
  • Flow Automation
  • Data Publishing plans
  • Communications
  • Turn over to Mike

I believe what happens in history is this the
old are always wrong and the young are always
wrong about what is wrong with them.

AQS Background
  • Collects air quality data (pollution and related
    information)
  • Data is used to determine non-attainment areas
    and by health researchers
  • Managed and operated in RTP, NC
  • 1,000 sites around the country
  • 200 parameters collected
  • Reporting schedule varies, but generally, data
    required 90 days after end of calendar quarter in
    which it was collected
  • We get almost 2M data points per week from State,
    local, and tribal agencies (several hundred
    files)
  • Highest volume through CDX

4
AirNow Background
  • Collects air quality data (pollution and related
    information) and forecasts
  • Data is used to inform public of immediate health
    concerns
  • Managed in RTP, NC
  • Operated in Sonoma, CA
  • 1,000 sites around the country (same as AQS)
  • 2 primary parameters collected, anything allowed
  • Reporting schedule every hour for data every
    day for forecasts
  • Data converted into near-real-time maps at
    http//www.airnow.gov/
  • Not yet on the Exchange Network

5
Status Continuing to Improve
  • AQS
  • Accepts data via Node since May 2005
  • Many formats
  • Legacy flat file
  • New flat file
  • Schema v1.0
  • Schema v2.0 (almost!)
  • New version of the schema will be released soon
    (responding to conformance review)
  • AQDE AQSv2
  • AirNow
  • Working to implement node at DMC
  • Will use same schema for air quality data (not
    forecast) submissions
  • Pilot project completed (q.v. Part 2)

When you break the big laws, you do not get
freedom you do not even get anarchy. You get
the small laws. -- G.K. Chesterton

New Schema
Progress is a comparative of which we have not
settled the superlative. -- G.K. Chesterton
  • Version 1 developed with a pure information
    engineering approach
  • Node submission to feds
  • Minimize instance document size
  • Version 2 developed for flexibility of exchange
  • ESAR compliant
  • Revamped structure
  • Flat versus hierarchical
  • Better facilitates non-federal (e.g,
    state-to-state) sharing
  • Focus was Air Quality not just AQS
  • Will incorporate data for AirNow exchanges
  • Testing plan / ability

XML Testing
AQS PROD
AQS Node
AQS QA
  • Two databases
  • AQS Production (AQSPROD)
  • AQS Quality Assurance (AQSQA)
  • AQSPROD database was backed up to AQSQA on
    4.8.2007
  • Data and passwords will be as of then (90 day
    exp.)
  • Contractors cannot get access
  • Call helpdesk with problems 866-411-4EPA

Submission Automation
The simplification of anything is always
sensational. -- G.K. Chesterton

Data Publishing
We look forward with enthusiasm because we are
afraid to look back. --
G.K. Chesterton
  • No node publishing yet
  • Users can get XML data from AQS as you get any
    other data
  • New system for dissemination AQS Data Mart
  • Prevent competition for resources
  • Uses CDX/EN web services
  • Node client in test
  • Same protocol as AQDE project
  • No FCD yet
  • Additional web services geared toward scientists
  • Additional schemas
  • Stylesheets
  • Client for human interaction
  • Will eventually include AirNow data
  • Technical issue with SOAP message size and
    physical memory of EPA and client hardware
  • Will then work on publishing from AQS
  • Smaller audience

Communications
  • Helpdesk
  • IPT calls
  • Every other Wednesday
  • May 09 is the next one
  • 300 pm eastern
