The research objective of the contribution of University of Bremen to the HALO CoMet mission is focusing on the first science question (SQ1, see HALO CoMet umbrella proposal): Can we identify and quantify (in a top-down approach) local sources of greenhouse gases such as power plants, coal mines, landfills, city plumes, or geological sources? This will be addressed by underflying of HALO CoMet carrying CHARM F over regions with strong localised point sources. Whereas HALO, due to its flight altitude and speed, will be able to only get a very few transects through plumes from areas with strong localised point sources, MAMAP on a lower and slower flying aircraft will provide the detailed local context of the area where strong localised point sources are expected. With MAMAP, maps of column averaged dry air mole factions of CO2 and CH4 (denoted XCO2 and XCH4) will be provided for scales of approximately 10x10 to 20x20 km2. Target areas are Berlin (CO2 city plume as well as two strong CO2 emitting power plants nearby) and the Upper Silesian Basin with several strong CH4 emitters on a relatively small arear. The data from the campaign will analysis and interpretated in terms of localisation of source positions and/or (depended on source density) source areas, as well as quantification of source strengths , using MAMAP and CHARM-F data. The data will further be validate by in-situ soundings performed with the in-situ instrumentation also installed on HALO (e.g.CH4, CO2, H2O; see also HALO CoMet White Paper). The interpretation will be supported by high resolution modelling in cooperation of MPI BGC in Jena. In addition, it will be investigated in how far MAMAP and COMET sensors constitutes an adequate instrumentation to validate future spaceborne missions such as OCO-2, Sentinel-5 Precursor, GOSAT-2, MERLIN, Sentinel-5, CarbonSAT, or ASCENDS. This will be addressed by coordinating wherever feasible campaign flights with satellite overpasses of those missions active in 2017 (OCO-2, Sentinel-5P, potentially GOSAT). Data interpretation of airborne remote sensing and in-situ data will be performed in comparison to the satellite observations.

不莱梅大学对 HALO CoMet 任务的贡献的研究目标集中在第一个科学问题（SQ1，参见 HALO CoMet 总体提案）：我们能否识别和量化（以自上而下的方法）当地温室气体来源例如发电厂、煤矿、垃圾填埋场、城市羽流或地质来源？这将通过携带 CHARM F 的 HALO CoMet 在具有强大本地点源的区域上空飞行来解决。鉴于 HALO 的飞行高度和速度，只能从具有强局部点源的区域通过羽流获取极少数横断面，而低速飞行飞机上的 MAMAP 将提供强局部源区域的详细局部背景。预计局部点源。通过 MAMAP，将提供比例约为 10x10 至 20x20 km2 的 CO2 和 CH4（表示为 XCO2 和 XCH4）的柱平均干燥空气摩尔派系图。目标区域是柏林（城市二氧化碳羽流以及附近两个二氧化碳排放量大的发电厂）和上西里西亚盆地，在相对较小的区域内有多个甲烷排放量较大的发电厂。来自活动的数据将使用 MAMAP 和 CHARM-F 数据，根据源位置和/或（取决于源密度）源区域的本地化以及源强度的量化进行分析和解释。数据将通过 HALO 上安装的现场仪器（例如 CH4、CO2、H2O；另请参阅 HALO CoMet 白皮书）进行的现场探测进一步验证。解释工作将得到与耶拿 MPI BGC 合作的高分辨率模型的支持。此外，还将研究 MAMAP 和 COMET 传感器在多大程度上构成了足够的仪器来验证未来的星载任务，例如 OCO-2、Sentinel-5 Precursor、GOSAT-2、MERLIN、Sentinel-5、CarbonSAT 或 ASCENDS。这将通过在 2017 年活跃任务（OCO-2、Sentinel-5P、可能是 GOSAT）的卫星立交桥上协调尽可能可行的战役飞行来解决。机载遥感和现场数据的数据解释将与卫星观测数据进行比较。
