Measurements, process studies and Modelling (MAMM) program: 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 consortium brings 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、过程研究与建模”（MAMM）项目系英国自然环境研究委员会（NERC）北极研究计划的一部分。该联盟汇聚了众多专业领域的人才，涵盖了从甲烷及其同位素、其他温室气体的测量，到通量测量，再到数值分析和建模的整个过程。项目对地面和航空采集的气体混合比（浓度）、同位素特征和来源通量进行了分析。过去及新的测量数据均采用一系列技术进行建模。通量数据被纳入JULES陆地表面模型中。大气建模，包括轨迹和逆建模，将有助于在局部/区域尺度上深化对北极排放在大规模全球大气变化中作用的理解。该项目由剑桥大学牵头，并与曼彻斯特大学、东安格利亚大学、伦敦皇家霍洛威学院、伦敦大学学院、生态与水文中心以及英国和国际合作伙伴（如气象局、挪威环境研究所、美国国家海洋和大气管理局等）共同协作。
