RAPID: Testing the Solar Occultation Flux Instrument on the Wyoming King Air

该项目包括在2017年夏末对怀俄明州King Air飞机上的科罗拉多大学机载太阳掩星通量（SOF）仪器进行修改和测试。该仪器在NSF/NCAR C130上的先前部署证明了其量化氨、氮氧化物和其他痕量气体排放通量的能力。 该仪器将特别有助于研究野火排放，这是2018年夏季美国西部更大规模实地活动的一部分。 森林火灾导致许多地区的能见度降低和空气质量下降。SOF可以通过测量整个羽柱剖面来量化来自区域源（例如森林火灾源）的痕量气体排放通量。结合风向/风速的测量，通过应用质量平衡法计算排放通量。该RAPID提案的紧迫性在于需要对仪器进行修改，并测试和证明在野火环境中部署仪器的可行性，然后再支持其在计划于2018年夏季进行的重大实地活动中的使用。 SOF对痕量气体柱的测量与计划于2018年从NSF/NCAR C130飞机上进行的详细采样具有高度互补性。

This project includes the modification and testing of the University of Colorado Airborne Solar Occultation Flux (SOF) instrument on the Wyoming King Air aircraft during the late summer of 2017. Prior deployment of this instrument on the NSF/NCAR C130 demonstrated its capability to quantify emission fluxes of ammonia, nitrogen oxides and other trace gases. The instrument will be especially useful in the study of wildfire emissions planned as part of a larger field campaign in the summer of 2018 in the Western US. Wildfires contribute to reduced visibility and the degradation of air quality in many regions.The SOF can quantify trace gas emission fluxes from an area source, such as a wildfire source, by measuring the entire plume column profile. In combination with measurements of wind direction/speed, the emission flux is calculated by applying the mass balance method. The urgency of this RAPID proposal consists in the need for instrument modifications and for testing and demonstrating the feasibility of deploying the instrument in a wildfire environment prior to supporting its use in a major field campaign scheduled for next summer in 2018. SOF measurements of trace gas columns are highly complementary to the detailed sampling that is planned from the NSF/NCAR C130 aircraft in 2018.
