The BB-FLUX project is part of a larger collaborative effort (WE-CAN) focused on the study of the emissions and evolution of western U.S. wildfire plumes. A field campaign is scheduled to take place in the late summer of 2018 near Boise Idaho. The emission fluxes of a number of gases will be measured and compared with model predictions. The results will provide significantly improved quantification of wildfire emissions and provide important new information to fire and fuel managers, and to air quality regulators.The University of Colorado airborne Solar Occultation Flux (SOF) instrument will be used to calculate quantitative fluxes for a large number of gases. Measurements will be made simultaneously above the aircraft, during aircraft transects below plumes, with fluxes being quantified using the mass balance method. The project combines remote sensing of CO and other trace gas columns by SOF (e.g., H2O, NO, NO2, NH3, HONO, HCHO, small VOCs, CH3OH, HCN, HCOOH, other small acids), temperature and humidity profiles, and plume injection height (Lidar), with select in-situ sampling (CO, CO2, H2O, O3, wind speed, particle size distributions).BB-FLUX has the following four objectives: 1) quantify emission fluxes of CO, CO2, other gases, and particle volume for different fuel types (boreal forest, temperate forest) and burn conditions (flaming, smoldering); 2) characterize plume injection height from plumes that travel decoupled from the ground (top of boundary layer, free troposphere), and evaluate predictions by atmospheric models; 3) study radical sources and secondary plume chemistry that leads to secondary production of O3 and changes in the particle size distribution as plumes age. Finally, SOF column measurements complement the detailed in-situ sampling of emission ratios on the C-130 aircraft. By probing similar fires using both aircraft, this project 4) explores synergistic benefits of remote sensing and in-situ observations to quantify speciated total emission fluxes from wildfires.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

BB-FLUX 项目是更大的合作项目 (WE-CAN) 的一部分，该项目专注于研究美国西部野火羽流的排放和演变。 实地考察计划于 2018 年夏末在爱达荷州博伊西附近进行。 将测量多种气体的排放通量并与模型预测进行比较。 结果将显着改进野火排放的量化，并为火灾和燃料管理人员以及空气质量监管机构提供重要的新信息。科罗拉多大学机载太阳掩星通量（SOF）仪器将用于计算大量的定量通量气体。 测量将在飞机上方、羽流下方的飞机横断面期间同时进行，并使用质量平衡方法对通量进行量化。 该项目结合了 SOF 对 CO 和其他痕量气体柱（例如 H2O、NO、NO2、NH3、HONO、HCHO、小量 VOC、CH3OH、HCN、HCOOH、其他小量酸）、温度和湿度剖面以及羽流的遥感喷射高度（激光雷达），并选择原位采样（CO、CO2、H2O、O3、风速、颗粒尺寸分布）。BB-FLUX 有以下四个目标： 1) 量化不同燃料类型（北方森林、温带森林）和燃烧条件（燃烧、阴燃）的 CO、CO2、其他气体和颗粒体积的排放通量； 2) 表征与地面（边界层顶部、自由对流层）分离的羽流喷射高度，并评估大气模型的预测； 3) 研究导致 O3 二次产生的自由基来源和二次羽流化学以及随着羽流老化而发生的颗粒尺寸分布变化。最后，SOF 柱测量补充了 C-130 飞机排放比率的详细现场采样。通过使用两架飞机探测类似的火灾，该项目 4) 探索了遥感和现场观测的协同效益，以量化野火的特定总排放通量。该奖项反映了 NSF 的法定使命，并通过使用基金会的评估进行评估，被认为值得支持。智力价值和更广泛的影响审查标准。
