Topics for part 1 status plans

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. -- G.K. Chesterton


Aqs background

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


Airnow background

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


Status continuing to improve

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

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

XML Testing

AQS PROD

  • 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

Submission Automation

The simplification of anything is always sensational.

Data publishing

We look forward with enthusiasm because we are afraid to look back. -- G.K. Chesterton

Data Publishing

  • 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

Communications

  • Helpdesk
