项目摘要

The INTAS project will investigate the import of pollutants by long-range transport into mid- and high-latitudes over Europe using an integrated analysis of satellite observations, model simulations, and aircraft measurements. The transport pathways of pollutants from source to receptor regions will be studied as well as the photochemical processing and changes in microphysical aerosol properties during transport. A particular focus will be on the impact of emissions of forest fires in Alaska and Canada and anthropogenic pollution from urban areas of North America on sensitive European receptor regions including the Mediterranean and the European sector of the Arctic. The implications of the pollution import on regional air quality, e.g. ozone concentrations, and radiative forcing will be studied.INTAS includes several innovative aspects. The use of satellite observations to monitor long-range transport will be facilitated by model-assisted retrievals of tropospheric columns and combined use of multiple satellite sensors. A novel high resolution Lagrangian model with photochemistry will be developed and used to investigate the composition changes in pollution plumes during transport. Lagrangian experiments will be analysed where air masses have been tagged with an artificial tracer to study the interplay of chemistry and mixing of the plumes with the environment. Parameterizations in a chemistry-transport model of important sources and sinks of reactive nitrogen will be improved by exploiting measurements from satellite and aircraft.

INTAS项目将利用对卫星观测、模型模拟和飞机测量的综合分析，调查污染物通过远距离迁移进入欧洲中高纬度地区的情况。将研究污染物从源到受体区域的传输途径以及传输过程中的光化学处理和微物理气溶胶特性的变化。将特别侧重于阿拉斯加和加拿大森林火灾的排放以及北美城市地区的人为污染对欧洲敏感受体区域的影响，包括地中海和北极的欧洲部分。将研究污染输入对区域空气质量的影响，例如臭氧浓度和辐射强迫。INTAS包括几个创新方面。将通过模型辅助对流层气柱反演和综合使用多个卫星传感器，促进利用卫星观测监测远距离传输。将开发一种新的高分辨率拉格朗日模型，并将其用于研究污染羽流在传输过程中的成分变化。将分析拉格朗日实验，其中空气质量已被标记人工示踪剂，以研究化学的相互作用和羽流与环境的混合。将利用卫星和飞机的测量数据改进活性氮重要源和汇的化学传输模式中的参数化。
