ATMOCHEM - POllution: MODeling and ObseRvatiOns (POMODORO)

尽管进行了大量的案例研究，但人们对通过生物质燃烧和人为来源造成的污染对对流层臭氧的全球影响和激进预算缺乏了解。此外，污染物向平流层下层输送的途径和相关性需要澄清。本项目将MIPAS高度分辨的各种一次和二次污染物（CO、C2H6、C2H2、PAN、HNO3、O3、HCN、CH2O等）的翼部测量和IASI臭氧和CO对流层柱测量与模式计算和数据同化相结合，以更好地了解污染物的来源、抬升、化学处理、远程输送和对流层-平流层交换。MIPAS对各种污染物的测量将通过羽流的化学成分来区分不同的污染源（工业/城市与生物质燃烧），利用不同来源的羽流具有不同的污染物比例这一事实，可以用作化学指纹。IASI的臭氧和CO测量将用于跟踪羽流传播。将特别注意污染物光谱数据的质量评估、改进和补充，这是遥感中的一个关键问题。该项目提供的观测将得到MOPITT、SCIAMACHY、MLS、ODIN、ACE以及加勒比地区飞机观测的补充，并将用于约束和验证热对流、污染物的远距离输送和化学处理、各种污染与对流层上层臭氧化学的相关性以及污染物侵入平流层下层的模拟。使用的工具包括化学输运模型（MOCAGE）、数据同化工具（moage - palm）、化学环流模型（ECHAM5/凌乱）和拉格朗日工具。目标是在全球范围内评估各种来源的污染的影响。

Despite numerous case studies, there is lack of knowledge about the global impact of pollution through biomass burning and anthropogenic sources on tropospheric ozone and the radical budget. Further the pathways and relevance of transport of pollutants into the lower stratosphere need clarification. This project combines altitude-resolved MIPAS limb measurements of various primary and secondary pollutants (CO, C2H6, C2H2, PAN, HNO3, O3, HCN, CH2O and others) and IASI ozone and CO tropospheric column measurements with model calculations and data assimilation to provide a better understanding of the sources, uplift, chemical processing, long-range transport and troposphere-to-stratosphere exchange of pollutants. MIPAS measurements of various pollutants will be used to distinguish different pollution sources (industrial/urban vs. biomass burning) by the chemical composition of plumes, taking advantage of the fact that plumes of different sources are characterized by different ratios of pollutants which can be used as chemical fingerprint. IASI ozone and CO measurements will be used to track plume propagation. Particular care will be devoted to quality assessment, improvement, and complement of spectroscopic data of pollutants, a key issue in remote sensing. Observations provided by this project will be complemented by MOPITT, SCIAMACHY, MLS, ODIN, ACE, as well as CARIBIC aircraft observations and will be used to constrain and verify modeling of pyroconvection, long range transport and chemical processing of pollutants, the relevance of various types of pollution to upper tropospheric ozone chemistry, and the intrusion of pollutants into the lower stratosphere. The tools to be used include chemical transport models (MOCAGE), data assimilation tools (MOCAGE-PALM), chemistry general circulation models (ECHAM5/MESSy), and Lagrangian tools. The goal is to assess the impact of pollution of various sources on a global scale.
