MAMM: Airborne Methane and Other Greenhouse Gases Measurements

The Methane and other greenhouse gases in the Artic - Measurements, process studies and Modelling (MAMM) project was a consortium as part of the NERC Artic Research Programme. This project used a range of expertise, from measurements of methane and its isotopes, and other greenhouse gases, through flux measurements to numerical analysis and modelling. Analysis of gas mixing ratios (concentrations), isotopic character, and source fluxes, both from the ground and aircraft. Both past and new measurements were modelled using a suite of techniques. Fluxes were implemented into the JULES land surface model. Atmospheric modelling, including trajectory and inverse modelling will improve understanding on the local/regional scale, placing the role of Arctic emissions in large scale global atmospheric change.

The project was led by the University of Cambridge, and in association with the University of Manchester, University of East Anglia, Royal Holloway, University of London, Centre for Ecology and Hydrology and UK and International partners (Met Office, NILU, NOAA, etc).

甲烷及其他温室气体在北极地区——测量、过程研究及建模（MAMM）项目系英国自然与环境研究委员会（NERC）北极研究计划的一部分。该项目汇聚了众多领域的专业才智，涵盖了从甲烷及其同位素、以及其他温室气体的测量，至通量测量，再到数值分析和模型构建的全过程。对气体混合比（浓度）、同位素特征及来源通量的分析，既包括地面观测，亦涉及航空测量。过去及新的测量数据均采用一系列技术进行建模。通量数据被整合至JULES陆地表面模型中。大气建模，包括轨迹和逆模型分析，将有助于提升对局地/区域尺度上的理解，并凸显北极排放在全球大气变化中的重要作用。项目由剑桥大学牵头，联合曼彻斯特大学、东安格利亚大学、伦敦皇家霍洛威学院、伦敦大学学院、生态与水文研究中心以及英国及国际合作伙伴（气象局、挪威国际环境研究所以及美国国家海洋和大气管理局等）共同实施。
