The Ambition of GreenFeedBack is to enhance knowledge of the GHG dynamics in the ecosystems and link GHG in terrestrial, freshwater and marine ecosystems to provide a solid basis for estimation of regional and global climate feedback processes taking human pressure on ecosystems into account. GreenFeedBack will study the processes in sensitive terrestrial, freshwater, coastal and marine areas of which some are hypothesized to be tipping elements in the climate system. Thus, we will primarily focus on high latitude terrestrial and freshwater systems, marine shelves and ocean areas and thereby advance the process-based representation of ecosystems in Earth System Models (ESM). The analysis will involve co-design between scientists and stakeholders. We will use data from the ICOS and ACTRIS stations in Europe and the GIOS, GEM and SMEAR network in Greenland and Finland as well as data from dedicated field and laboratory studies. The enhanced knowledge will be used to improve descriptions of the GHG processes for implementation in ecosystem models and ESMs. Hence, GreenFeedBack will improve and apply ecosystem- and Earth System models to advance our understanding of GHGs effect on climate variability over different time horizons.

GreenFeedBack的目标是加强对生态系统中温室气体动态的了解，并将陆地、淡水和海洋生态系统中的温室气体联系起来，为评估区域和全球气候反馈过程提供坚实的基础，同时考虑到人类对生态系统的压力。GreenFeedBack将研究敏感的陆地、淡水、沿海和海洋地区的过程，其中一些地区被假设为气候系统的关键因素。因此，我们将主要关注高纬度陆地和淡水系统、海洋陆架和海洋区域，从而推进地球系统模型(ESM)中生态系统的基于过程的表示。分析将涉及科学家和利益相关者之间的共同设计。我们将使用欧洲的ICOS和ACTRIS站以及格陵兰和芬兰的GIOS、GEM和涂片网络的数据，以及专门的实地和实验室研究数据。增强的知识将用于改进对温室气体进程的描述，以便在生态系统模型和生态系统管理中实施。因此，GreenFeedBack将改进和应用生态系统和地球系统模型，以促进我们对不同时间范围内温室气体对气候变异性影响的理解。
