BlueSky_map.pngMethods for Determining Mixing Height, by Matthew Fearon and Robyn Heffernan

Now available on the Southern Fire Exchange website. This webinar features researcher Matthew Fearon of the Desert Research Institute discussing recent research investigating various methods for estimating atmospheric mixing height. Following his presentation Robyn Heffernan with the National Weather Service discussed NWS plans for their mixing height determination procedures.

BlueSky_map.pngDecember 17, 2015, Webinar: 'Impairment’ – A New Metric to Track Progress under the Regional Haze Rule, by Scott Copeland (FS)

US EPA’s 1999 Regional Haze Rule (RHR) is the only Clean Air Act program aimed solely at protecting the visual air quality, or “visibility” in many wildernesses, national parks, and wildlife refuges. Progress is being made towards the Clean Air Act goal of no manmade visibility impairment in class I areas, however, haze from wildfires and prescribed fires has made it difficult for many states to demonstrate that progress. While the largest recent effects from smoke are seen in western states, fossil fuel emissions reductions in the east will lead to the same issue arising in eastern states in the near future.

For the past year, US EPA has collaborated with federal land managers, and consulted with state air agencies to develop a new metric that focuses attention on anthropogenic emissions. The new metric can be easily calculated from IMPROVE data, and provides a new method for states to demonstrate progress towards the Regional Haze Rule goal.

EPA Resource Page.pngNovember 18, 2015, New Ozone Resources Page

In October the EPA strengthened the National Ambient Air Quality Standards for Ozone. This new standard will have implications for the wildland fire community. The Ozone Resources page highlights regulatory information from the EPA, maps of potential non-attainment areas, testimonies, and the latest reports and research collected by the NWCG Smoke Committee.

BlueSky_map.pngNovember 10 2015, Proposed Revisions to the Exceptional Events Rule

The EPA proposed revisions to the 2007 Exceptional Events Rule (EER) as of November 10. To view the proposed rule see the EPA proposal. For additional information, draft guidance and a fact sheet, visit the EPA's Proposed EER Revision and Draft Guidance Page. Written comments on the proposal and its draft guidance may be sent to EPA by January 19, 2016.

EPA Resource Page.pngOctober 1 2015, New Primary Ozone Standard for NAAQS

In October 2015 the EPA strengthened the National Ambient Air Quality Standards for ozone to 70 parts per billion. This new standard will have implications for the wildland fire community. The EPA regulatory action page for ozone contains the final rule, memo for implementing the new standard, regulatory impact analysis, maps and tables, fact sheets, and technical documents.

Domitrovich_workshop.jpgWorkshop: Wildland Fire Smoke Health Effects Research and Tools to Inform Public Health Policy and Recommendations

Summary and presentations now available through the Emission and Smoke Portals Health Effects Research webpage. The four hour workshop was presented during the April 2015 International Wildland Fire conference in Boise Idaho. Experts discussed new science on health impacts of smoke and opportunities to further inform and support development of health policy and recommendations. The workshop included a discussion of new and emerging health research to inform public health policy, presentations focusing on guidelines and recommendations to reduce the public health impacts of smoke exposure, and presentations on new tools for estimating smoke exposure and forecasting.

emission_factor_pic.pngPresentation: Wildland Fire Emission Factors - Shawn Urbanski, Research Scientist with the USDA Forest Service Rocky Mountain Research Station presented the latest research in emission factors. Emission factors are a key component to estimating emissions of trace gases and particulates from fire. Shawn discussed how emission factors are measured, factors that influence the measurements (e.g. fire combustion phase, vegetation type), lab/field/airborne/tower measurement techniques, and the new suite of non-methane organic compounds now detectable.

National Fire Danger Rating System Updates - In September of 2014 the National Wildfire Coordinating Group (NWCG) approved updates to the US National Fire Danger Rating System (NFDRS). These included reducing the number of fuels models, the incorporation of a Growing Season Index to compute live fuel moistures and the incorporation of the Nelson model to compute defined dead fuel moistures. The NWCG Smoke Committee has reviewed two presentations on the proposed changes to the NFDRS, these are available below:

3/3/15 Southwest Wildland Fire Smoke Workshop Presentations Now Available: Presentations from the Nov. 2014 Smoke Workshop are now available at the Southwest Fire Science Consortium workshop homepage.

Canadian National Smoke Forum The National Smoke Forum was held on October 10, 2014 in Halifax, NS. The objective of this meeting was to conduct an information exchange with users of smoke forecasting systems such as BlueSky for Canada. The meeting was held in conjunction with the Wildland Fire Canada 2014 conference to maximize participation from the fire community and well as to introduce health agencies to the fire community. Forty-two people attended this meeting along with 35 others who connected remotely. Attendees included the fire, environment, and health and safety experts from federal and provincial agencies as well as the US. A result of this meeting is an effort to define a national standing forum or national coordinating body for smoke and air quality that can help future direction of smoke forecasting and research as well as understanding the health impacts in Canada.

Copies of the presentations and posters can be found at: 2014 National Smoke Forum

15 Sept 2014 - Where the wildfires are: if there's smoke, there are costly health problems

Scientists fear that climate change could lead to more wildfires – and to lingering, expensive, public health crises as smoke spreads thousands of miles away from the actual fire sites. - Guardian.com article by Amy Westervelt
