Technical Support System Reviewhttp://vista.cira.colostate.edu/tss/

RPO Monitoring/Data Analysis Workgroup Conference Call

April 12, 2007

TSS Goals

• Provide a single web-based location for:– Access and display of regional haze

technical data– Reference location to support individual

regional haze plans

• Document technical methods for regional haze plans

TSS Goals

• Ongoing tracking and assessment– Emissions reductions– Monitoring data for regional haze and other

air quality programs

• Adapt to and serve future regional technical needs of WRAP members

WRAP Technical Data Information Centers

Visibility Information Exchange Web System (VIEWS): VIEWS provides on-line access to monitoring data, research results and special studies related to visibility. http://vista.cira.colostate.edu/views/

Regional Modeling Center: The WRAP’s Regional Modeling Center at the University of California Riverside provides state and tribal agencies with sophisticated modeling of regional haze in the Western United States. http://pah.cert.ucr.edu/aqm/308/

Emissions Data Management System: An emission inventory data warehouse for states and tribes. The system provides a consistent, complete and regional approach to emissions data management and tracking. http://www.wrapedms.org/

Causes of Haze Assessment: A detailed analysis of ambient monitoring data for regional haze in the WRAP region. http://www.coha.dri.edu/

The Technical Support System integrates a number of different information resources under one web-based umbrella. http://vista.cira.colostate.edu/tss

TSS Overview

• Interactive tools to support SIP writers’ needs• Graphs• Tables• Maps

• Incorporates Tribal areas

• Data tables available for download – Analysts can examine data and reformat graphics

as required

Home Page

Resources Page

Data results and standard displays for monitoring, emissions, and modeling analyses

Methods Page

Summary documents describing the technical methods used in monitoring, emissions, and modeling analyses

Site Selection

Selections include one or more individual Class I areas, all in a state, or tribal lands represented by IMPROVE monitors

Reasonable Progress Support Page*

Designed as a starting point for SIP writers to access and compile technical analysis products to support demonstrations of reasonable progress

*(currently under revision; formerly the Weight of Evidence Checklist page)

Monitoring Data Page

Monitoring data review choices include:

•Parameter(s)

•IMPROVE equation

•Year(s)

•Various averaging periods

•Deciview or species glideslopes

Modeling Data Page

Modeling data review choices similar to the Monitoring page plus:

•Modeling scenario(s)

•Model performance evaluation

•Model projections

Paired bars: 2002 (left) vs. 2018 (right)

Emissions Data Page

Emissions data page under development. Currently exists as a series of spreadsheets.

Source Apportionment – SOx/NOx Tracer

SOx/NOx tracer options:

•Emissions scenario(s)

•Source categories

•Source regions

•Compare with state emissions (coming soon)

•Identify important regions

•Review temporal contributions

Available for all major pollutants, products include:

•Sets of maps

•Source region/category results

Source Apportionment – Weighted EmissionsWeighted Emissions Potential (WEP) analysis combines emissions with baseline period meteorological residence times to help identify areas of potential contribution

Source Apportionment – Organic Aerosol Tracer

This tool can be used to identify periods of potential fire impact. It separates modeled organic aerosol into:

•Anthro. secondary (red)

•Biogenic secondary (green)

•Anthro. + biogenic primary (blue)

Class I area (above); Urban area (right)

• TSS review and clean-up in progress

• TSS training – Webinar session for WRAP planners on April 13– Tribal session week of June 4 – Workshop: June 19-20

• IMPROVE data updates for 2005 and 2006

• Link with other web sites/data nodes:– Fire Emissions Tracking System (FETS)– Emissions Data Management System (EDMS)
