The TSS project team has completed the following updates in support of regional haze planning:

1. The Class I Area Summary Table is now available for each Class I area in the WRAP region. It shows the monitoring, emissions, source apportionment and visibility projections data for the Best and Worst visibility days. The table is in HTML format – easily copied and pasted into Excel. The summary table calculates metrics to support regional haze analysis by monitored and emissions species, total light extinction, and deciview.
2. The Emissions Review Tool now displays regional emissions summaries along with individual states' data. The geographic regions summarized are the WRAP, CENRAP, Eastern US (Midwest RPO + MANE-VU + VISTAS), Canada, Mexico, and separate displays of Offshore Shipping emissions for the eastern Pacific Ocean and western Atlantic Ocean/Gulf of Mexico areas.

The TSS project team has completed the following updates in support of regional haze planning:

1. The Plan02d visibility modeling data results have been uploaded. These data can be reviewed on the Visibility Modeling Results tool, as well as being used in the Visibility Projections tool. Users can view model results by scenario, either as individual scenarios or as preselected pairs.
2. SOx/NOx Tracer (PSAT) data for all WRAP, CENRAP, and selected Midwest RPO Class I area monitoring sites are now available.
3. The Weighted Emissions Potential data set has been revised to include Plan02d and PRP18a results only. The PRP18a results are now normalized to Plan02d results so that actual changes in weighted emissions between the scenarios will be evident.
4. The Parameter selection list in the Emissions Review tool has been expanded to include Sulfur Dioxide, Sulfur Oxides (gas and particulate), Nitrogen Oxides (gas), and Nitrogen Oxides (gas and particulate) because there is a need for these different selections.
5. The following rules for accessing data results have been implemented, due to the nature of the TSS data and its applicability across the U.S.:
• Monitoring data are available for all IMPROVE sites on the TSS.
• SOx/NOx Tracer (PSAT) data are available for all WRAP, CENRAP, and northwestern Midwest RPO sites.
• WEP data are available for all WRAP sites and GUMO (a CENRAP region site which represents Carlsbad Caverns, NM).
• Visibility Projections are available for all WRAP sites and GUMO (a CENRAP region site which represents Carlsbad Caverns, NM).
