superfog presentation map thumbnail.pngWebinar Series - Wildland Fire Smoke and Roadway Visibility: Predict, Prepare and Avert Accidents, by Gary Achtemeier, Gary Curcio, and Matthew Fearon 

 This webinar series reviews present and future efforts made by the US Forest Service and others to understand this important topic. The information and tools developed specifically to address wildland fire smoke, smoke transport, and the likelihood of superfog formation are presented in three parts:

Part 1 - Superfog: How it forms, where it forms, where it goes, what to do (.mp4)

Part 2 - Weather information & tools available to stay ahead of superfog events or severely reduced roadway visibility (.mp4)

Part 3 - Planned Burn (PB) Piedmont Web Tool - Estimating Superfog potential from Smoldering Combustion (.mp4)

BlueSky_map.pngWebinar - Indoor Air Quality During Wildland Fires: Experience and Research, by Kris Ray and Shelly Miller

A webinar containing two presentations on indoor air quality. The first, from Kris Ray, evaluates indoor air quality during very high ambient PM2.5 concentrations at the Colville Reservation in Washington State, which resulted from the 2015 wildfire season. The second presentation, from Shelly Miller, evaluates the impact of indoor air cleaning devices during wildland fires.

FASMEE_webinar2.pngWebinar - Fire and Smoke Model Evaluation Experiment (FASMEE), by Roger Ottmar, Sim Larkin, Tim Brown, and Nancy French 

This webinar will review the objectives and progress of the multi-agency Fire and Smoke Modeling Experiment (FASMEE) project. The primary objective of FASMEE is to gather observational data needed to evaluate and advance fire and smoke modeling systems. 

Presentation title slide.Finding the Balance: Wild Fire, Prescribed Fire, Forest Health, Public Health

A series of presentations in which experts explore the trade-offs between wildfire, prescribed fire, forest health, and public health in a one day public forum. This seminar event was hosted by the University of British Columbia on April 18th, 2016. 

 

SE Pine emissionsEmission Factors in SE Pine Grasslands, by Kevin Robertson

Particulate matter (PM) emission factors (EFPM), which predict PM emissions per biomass consumed, have a strong influence on PM emission inventories. PM < 2.5 mm diameter (PM2.5) is of special concern for human health. EFPM2.5 is typically held constant for the region or general fuel type being assessed. This study used structural equation modeling (SEM) to measure effects of fire environment variables on EFPM2.5 in U.S. pine-grasslands to refine their application in emission inventories. An a priori model was tested using 41 prescribed burns in Florida and Georgia, USA with varying years since previous fire, season of burn, and fire direction of spread. The SEM showed EFPM2.5 to be higher in burns conducted at higher ambient temperatures, corresponding to later dates from winter to summer and increases in live herbaceous vegetation and ambient humidity, but not total fine fuel moisture content. Pine needles had the strongest positive effect on EFPM2.5, and grass had a negative effect on EFPM2.5. Results of the study suggest that timber thinning and frequent prescribed fire minimize EFPM2.5 and total PM2.5 emissions on a per burn basis. Further development of PM emission models should consider adjusting EFPM2.5 as a function of these common land use variables. Looking to download a copy?

Presentation title slide.Methods 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.

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.

ARA_PL.jpgWildland Fire Air Quality Response Program: This 30 minute presentation describes the Wildland Fire Air Quality Response Program and examples of its use. Presented by Pete Lahm, USFS Fire and Aviation Management. (MP4 file for viewing in Firefox)(WMV file for viewing in IE).

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.

NFDRS.pngNational Fire Danger Rating System Update (YouTube link) - 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:

-What are the impacts, implications and/or collateral effect of NFDRS proposed changes to itself and other potential applications outside wildfire preplanning, suppression response arena?, Gary Curcio, IPA. (PowerPoint Version with Notes for Review) (PDF Version)

Southwest Wildland Fire Smoke Workshop Presentations Now Available: Presentations from the November 2014 Wildland Fire Smoke Workshop are now available via 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.
