Overview

The group reviewed minutes from the previous call. Since the last call, Rodger and Zac reviewed the MPE products list provided by Rebecca during the last call and added annotations and links to IWDW products, if available. The revised list was presented to the Tools Group during today's call.

Rodger walked the group through the IWDW tool development document. Major revisions to IWDW tools were the addition of SA modeling results; in particular the recent additions listed in the Current Tools Section of the agenda, above. The IWDW Development team will add a selection interface that allows users to select and distinguish the various SA products.

Another addition to the IWDW was a prototype MPE metrics tool that displays aggregate statistics from model-to-obs comparisons. Shawn gave a demo of the tool, illustrating how values for various metrics can be sorted to show a range of model performance for spatial averages across state and modeling domain, and annual and monthly temporal averages . The tool currently displays data for 2011b CAMx and CMAQ MPE at 4 and 12km domains. Feedback on the tool included: addition of GIS driven selection/display interface (TM); addition of links to representative static graphics on the MPE plots tool (RA); comments that aggregate statistics are not particularly useful because they do not represent episodes or sites that may be of interest for NAAQS or are that indicate localized model performance issues (GT).

A discussion ensued on how EPA is moving away from relying on benchmarks for MPE, and is focusing more on site and time specific representations of model performance, such as spatial plots overlaid with ambient data, and time series plots that allow for episodic selection.

TM made the suggestion that a top level menu of what the tools are and how they are useful to the MPE process would be a worthwhile addition to the IWDW website.
