This series of two webinars 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. The first session will be focused on screening the AQS data for exceedances above "normal" values and to indicate potential smoke or dust causes. The webinars and the associated wiki workspace are provided to give States and EPA Regions the opportunity to ask questions and provide feedback on how to improve the EE DSS. 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.
During the first 90-minute webinar we will cover the following topics:
The approach of EE DSS to address the clauses required by the Exceptional Event Rule;
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 (these are not "official") for EE flagging for 2010-2012. Based on this screening, States can identify and select candidate samples for EE flagging, to be submitted to EPA by the July 1, 2013 deadline. The anticipated outcomes and benefits of the EE Decision Support will include: reduction of the effort required by the States for EE flagging as well as a simpler and more uniform EE flag evaluation process by the EPA Regions.
This webinar is hosted by CAPITA at Washington University, ESIP Federation AQ Workgroup.
