  1. Overview of the Fire Lab at Missoula Experiments (FLAME)

    The Fire Lab at Missoula Experiments (FLAME) used a series of open biomass burns, conducted in 2006 and 2007 at the Forest Service Fire Science Laboratory in Missoula, MT, to characterize the physical, chemical and optical properties of biomass combustion emissions. Fuels were selected primarily based on their projected importance for emissions from prescribed and wild...

  2. Optical closure experiments for biomass smoke aerosols

    A series of laboratory experiments at the Fire Laboratory at Missoula (FLAME) investigated chemical, physical, and optical properties of fresh smoke samples from combustion of wildland fuels that are burned annually in the western and southeastern US The burns were conducted in the combustion chamber of the US Forest Service Fire Sciences Laboratory in Missoula,...

  3. Essentials of multiangle data-processing methodology for smoke polluted atmospheres

    Essentials for investigating smoke plume characteristics with scanning lidar are discussed. Particularly, we outline basic principles for determining dynamics, heights, and optical properties of smoke plumes and layers in wildfire-polluted atmospheres. Both simulated and experimental data obtained in vicinities of wildfires with a two-wavelength scanning lidar are...

  4. Brown carbon in tar balls from smoldering biomass combustion

    We report the direct observation of laboratory production of spherical, carbonaceous particles - "tar balls" - from smoldering combustion of two commonly occurring dry mid-latitude fuels. Real-time measurements of spectrally varying absorption Angstrom coefficients (AAC) indicate that a class of light absorbing organic carbon (OC) with wavelength dependent...

  5. Validation of smoke plume rise models using ground based lidar

    Biomass fires can significantly degrade regional air quality. Plume rise height is one of the critical factors determining the impact of fire emissions on air quality. Plume rise models are used to prescribe the vertical distribution of fire emissions which are critical input for smoke dispersion and air quality models. The poor state of model evaluation is due in...
