This webinar will introduce the Exceptional Event Decision Support System (EE DSS) of which purpose is to identify and to document observations that are candidates for exceptional event flagging. This session is focused on screening the AQS data for exceedances above "normal" values and to indicate potential smoke or dust causes.  Based on this screening, States can identify candidate samples for EE flagging.

This webinar will introduce the Exceptional Event Decision Support System (EE DSS) of which purpose is to identify and to document observations that are candidates for exceptional event flagging. This session is focused on screening the AQS data for exceedances above "normal" values and to indicate potential smoke or dust causes. A second webinar is planned for the end of May on the same topics, incorporating feedback from State analysts and pursuing further flagging use cases. The 90-minute webinar we will cover the following topics:

  • Formulation EE DSS in support of EE Rule implementation;
  • Datasets (FRM, satellite, model) and tools used in the EE DSS
  • Analysis approach: finding exceedances and those above normal variations;
  • Suggested exceptional (dust or smoke) sources for candidate samples
  • Demonstration of specific flagging examples

The main output of this decision support effort will be a national-scale list of candidate samples for EE flagging for 2010-2012. These are not "official"; the selection of the submitted flagged samples is the responsibility States. The anticipated outcome of the


Based on this screening, States can identify and select candidate samples for EE flagging, to be submitted by the July 1, 2012 deadline.


Webinar Outline

The hour and a half webinar will have three parts:

Intro

  1. What are exceptional events?
    • Description of steps (1) state observation (2) compare to standard - Ozone (daily max), PM2.5 (daily max, yearly average), PM10 (daily max) (3) Four steps that mgmt has to consider
  2. We have tool set that are nationally applicable for both flag id and documentation therefore there is a decision support system that is to be applicable to any of the exceedance types, regardless of cause, pollutant, and of region.
  3. Identify two dates flag submission (July 1) and documentation submission (Dec. 15)
  4. Priority is on screening for flagging event and what is the potential cause - categories
  5. Intro to the EE DSS by Rudy Husar, Washington University;

EE DSS is to screen for exceedances from all four standards (those above normal variations) and identify the type of cause (by EPA category).

EE DSS

Describe steps and how EE DSS deals with them

  1. Exceedance
  2. Exceeding normal variation
  3. Exploration of potential causes (Dust/smoke- NAAPS; Fire pixels, wind speeds etc, console)

Use Cases

  1. Hands-on session to try the EE DSS for your own State;
    1. List of all exceedances for each of standards above normal and corresponding "high normal" value in 2012 to see how far above normal you are; cut-off for how far above normal is flexible. - to be distributed
    2. Compare list to NAAPS dust/smoke
      1. Some easily attributable
      2. Left over neither dust or smoke
  2. Wrap-up Q&A
