生物质燃烧是与空气质量和气候有关的微量气体和气溶胶的一个重要和日益增加的来源。痕量气体和气溶胶的生物质燃烧通量测量（BB-FLUX）现场活动在2018年太平洋西北野火季节（7月至9月）期间在怀俄明州国王航空研究飞机上部署了科罗拉多大学机载太阳掩星通量（CU AirSOF）仪器。CU AirSOF使用短波红外波长跟踪太阳，即使在浓烟中也能最大限度地减少烟雾颗粒的散射，并使用傅里叶变换红外光谱（FTS）测量中红外波长处多种痕量气体的柱吸收。该仪器的描述，特点，并使用共定位地面遥感和机载原位数据集进行评估。垂直柱密度（VCD）测量结果与一氧化碳的固定高分辨率FTS一致（CO，斜率在2%以内），甲醛（甲醛，3%），甲酸（HCOOH，18%），乙烷（C2 H6，4%）、氨（NH3，4%）、氰化氢（HCN，10%）和过氧酰基硝酸酯（PANFTS，1%;我们将分子PAN与PANFTS区分开，PANFTS包括类似的分子并且通过FTS测量为总和）。在协调使命的兔子脚火附近的博伊西，爱达荷州的VCD消化成归一化的过剩柱比（NEMR）的机载VCD测量进行了比较，在现场测量上的NSF/NCAR C-130飞机。来自CU AirSOF的柱NEMR，表示为VCD相对于背景的增强并归一化为CO增强，发现对于HCHO、甲醇（CH 3OH）、乙烯（C2 H4）、C2 H6、NH 3和HCN，在20%内与原位NEMR一致，对于HCOOH和PAN，在30-66%内与原位NEMR一致。CU AirSOF集成了羽流异质性，本质上是校准的，并提供了一个创新的，灵活的，定量的工具来测量野火的排放质量通量。
Biomass burning is an important and increasing source of trace gases and aerosols relevant to air quality and climate. The Biomass Burning Flux Measurements of Trace Gases and Aerosols (BB-FLUX) field campaign deployed the University of Colorado Airborne Solar Occultation Flux (CU AirSOF) instrument aboard the University of Wyoming King Air research aircraft during the 2018 Pacific Northwest wildfire season (July–September). CU AirSOF tracks the sun even through thick smoke plumes using short-wave infrared wavelengths to minimize scattering from smoke particles, and uses Fourier transform infrared spectroscopy (FTS) to measure the column absorption of multiple trace gases at mid-infrared wavelengths. The instrument is described, characterized, and evaluated using colocated ground-based remote sensing and airborne in situ data sets. Vertical column density (VCD) measurements agree well with a colocated stationary high-resolution FTS for carbon monoxide (CO, slope within 2%), formaldehyde (HCHO, 3%), formic acid (HCOOH, 18%), ethane (C2H6, 4%), ammonia (NH3, 4%), hydrogen cyanide (HCN, 10%), and peroxyacyl nitrate (PANFTS, 1%; we distinguish the molecule PAN from PANFTS, which includes similar molecules and is measured as a sum by FTS). Airborne VCD measurements are compared with in situ measurements aboard the NSF/NCAR C-130 aircraft during a coordinated mission to the Rabbit Foot Fire near Boise, Idaho by digesting VCDs into normalized excess column ratios (NEMRs). Column NEMRs from CU AirSOF, expressed as VCD enhancements over background and normalized to CO enhancements, are found to agree with the in situ NEMRs within 20% for HCHO, methanol (CH3OH), ethylene (C2H4), C2H6, NH3, and HCN and within 30–66% for HCOOH and PAN. CU AirSOF integrates over plume heterogeneity, is inherently calibrated, and provides an innovative, flexible, and quantitative tool to measure emission mass fluxes from wildfires.
