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项目是一个更大的合作项目（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。 现场活动计划于2018年夏末在爱达荷州附近的博伊西举行。 将测量若干气体的排放通量，并与模式预测进行比较。 研究结果将大大改善野火排放的量化，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。科罗拉多大学的机载太阳掩星通量（SOF）仪器将用于计算大量气体的定量通量。 测量将在飞机上方和羽流下方的飞机断面上同时进行，使用质量平衡法对通量进行量化。 该项目结合了SOF对CO和其他痕量气体柱的遥感（例如，H2O、NO、NO2、NH3、HONO、HCHO、小VOC、CH 3OH、HCN、HCOOH、其他小酸）、温度和湿度剖面以及羽流注入高度（激光雷达），并选择现场采样（CO，CO2，H2O，O3，风速，粒度分布）.BB-FLUX有以下四个目标：1）量化不同燃料类型的CO、CO2、其他气体和颗粒体积的排放通量（北方森林，温带森林）和燃烧条件（燃烧、阴燃）; 2）表征与地面分离的羽流的羽流注入高度（边界层顶部，自由对流层），并评估大气模型的预测; 3）研究导致O3二次生成的自由基源和二次羽流化学，以及随着羽流年龄的增长，颗粒大小分布的变化。最后，SOF柱测量补充了C-130飞机上排放率的详细现场采样。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，以量化野火的物种总排放通量。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
