The present proposal aims at two objectives. The first objective addresses the participation of the mini-DOAS instrument in the HALO missions WISE, CAFE, EmerGe, and CoMet, which are planned for the period mid-2016 to mid-2019. The second objective concerns the spectral retrieval of the data not yet processed, the concentration and profile retrieval of the targeted gases, their interpretation in conjunction with complementary measurements, and the dissemination of the obtained results. For the latter study three scientific objectives have been identified: 1. Identification and quantification of the sources and sinks of NOx and the photochemistry NOy in the troposphere and lower stratosphere (UTLS) for air masses of different origins (e.g., clean and pristine air versus NOx polluted air). For this study NO2 (and when present HONO) measurements of the mini-DOAS instrument are taken together with complementary measurements (AENEAS, AIMS, .. ) of NOy species (NO, total NOy, and HNO3). 2. An investigation on the relevance of volatile organic compounds for oxidation capacity of clean and pristine air versus polluted air, whereby mini-DOAS measurements of CH2O (and potentially C2H2O2) and complementary measurements of VOCs and CO are taken to test the oxidation mechanism VOC -> CH2O -> CO. 3. An assessment of the budget and photochemistry of bromine from mini-DOAS measured of BrO (and photochemical modelling to calculate total inorganic bromine from measured BrO) together with measurements of organic brominated species (by the University of Frankfurt) within the UTLS. All these studies will be used to test the predictions of different global chemistry transport models (CTMs) (EMAC, CLAMS, TOMCAT/SLIMCAT, ...) for the investigated species.

本建议旨在实现两个目标。第一个目标涉及小型DOAS仪器参与HALO任务WISE，CAFE，EmerGe和CoMet，计划于2016年中期至2019年中期。第二个目标涉及尚未处理的数据的光谱反演、目标气体的浓度和轮廓反演、结合补充测量对其进行解释以及传播所获得的结果。对于后一项研究，确定了三个科学目标：1。确定和量化对流层和平流层下部不同来源的气团（例如，清洁和原始的空气相对于NOx污染的空气）。对于这项研究，NO2（和当存在HONO时）测量的迷你DOAS仪器与补充测量（AENEAS，AIMS，.. NOy种类（NO、总NOy和HNO 3）。2.对挥发性有机化合物与清洁和原始空气相对于污染空气的氧化能力的相关性进行调查，从而采取CH 2 O（和潜在的C2 H2 O2）的微型DOAS测量以及VOC和CO的补充测量来测试氧化机制VOC -> CH 2 O-> CO。通过微型DOAS测量的BrO（和光化学建模，根据测量的BrO计算总无机溴）以及UTLS内有机溴化物质的测量（由法兰克福大学进行），评估溴的预算和光化学。所有这些研究将用于测试不同的全球化学传输模式（CTM）（EMAC，CLAMS，TOMCAT/SLIMCAT，.）的预测。对于被调查的物种。
