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项目是一项更大的合作努力（We-Can）的一部分，该努力重点是研究美国西部野火李子的排放和进化。 计划于2018年夏末在爱达荷州的博伊西（Boise Idaho）举行一次实地运动。 将测量许多气体的发射通量，并将其与模型预测进行比较。 该结果将为野火排放的量化提供明显改进的量化，并为火灾和燃料管理者和空气质量调节器提供重要的新信息。 在飞机样带下方的羽毛下方，将同时进行测量，并使用质量平衡方法对通量进行量化。 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分布）.bb-flux具有以下四个目标：1）量化CO，CO2，其他气体和颗粒体积的发射通量（北方森林，温带森林）和燃烧条件（燃烧，闷烧）； 2）表征羽状注入的高度，从与地面（边界层的顶部，自由对流层）分离的羽流中，并通过大气模型评估预测； 3）研究激进源和二次羽流化学，导致O3的继发性产生以及粒度分布随着年龄的年龄而变化。最后，SOF柱测量值补充了C-130飞机上排放比的详细原位采样。通过使用两架飞机探测类似的火灾，该项目4）探索遥感和原位观察的协同益处，以量化野火的指定总排放通量。该奖项反映了NSF的法定任务，并认为通过使用该基金会的知识分子和更广泛的影响来评估CRITERIA的评估。
