Eurasian Boreal Network for land - atmosphere - climate interactions (BORNET-Eurasia)

欧亚北部地区变暖的速度比全球平均速度快3倍，使其成为识别和了解陆地-大气-气候相互作用和反馈的优先区域。这些高纬度地区的大部分变暖是由黑碳和臭氧等短暂的气候污染物(SLCP)推动的。在欧亚北部地区观测到的SLCP严重不足，这给我们提高认识带来了重大挑战。该提案旨在建立能力，以提高对欧亚高纬度地区可持续土地利用方案预算和气候反馈的理解。这将通过建立欧洲和俄罗斯科学家网络以及利用现有观测和全球模型模拟来推动未来在欧亚北部地区进行大规模野外观测实验来实现。我们将利用NERC现有的投资，对我们正在进行的欧洲污染出口研究和全球模式中大气成分的评估进行研究，为新的研究重点提供科学动力和方向。我们将在欧洲和俄罗斯的研究人员网络之间建立新的合作关系，并加强现有的合作关系。通过综合现有观测和多模型模拟，我们将激发对未来观测的需求，并对需要更好理解的过程进行优先排序。在我们的网络中，我们将举办一些研讨会，讨论a)现有的数据综合，b)模型-观测比较，c)欧亚北部地区未来的数据需求，以及d)未来飞机实地作战的计划。此外，我们将对俄罗斯莫斯科附近的中央航空观测站进行范围考察，以评估联合飞机行动不同战略的可行性，考虑到联合作战和通信的后勤、飞机行动的地缘政治限制以及联合飞行的试验战略等问题。该项目的总体最终结果将是形成一个由国际科学家组成的协调一致的社区，这些科学家在我们对短期气候污染物的了解、观测的优先事项以及未来在欧亚北部地区发展大型观测网络和大型实地项目的战略方面都有很强的知识基础。

The Eurasian Boreal region is warming 3 times faster than the global mean making it a priority region for identifying and understanding land-atmosphere-climate interactions and feedbacks. Much of the warming at these high latitudes is driven by short-lived climate pollutants (SLCPs) such as black carbon and ozone. There is a severe paucity of observations of SLCPs over the Eurasian Boreal region presenting a major challenge to improving our understanding. This proposal aims build capability for improving understanding of SLCP budgets and climate feedbacks in the Eurasian high latitudes. This will be achieved through the establishment of a network of European and Russian scientists, and exploitation of existing observations and global model simulations to motivate future large-scale field observation experiments in the Eurasian boreal region. We will leverage existing NERC investment in our ongoing research into European pollution export and evaluation of atmospheric composition in global models to provide scientific impetus and direction for new research priorities. We will build new, and strengthen existing collaborations between a network of researchers across Europe and Russia. By synthesising existing observations and multi-model simulations, we will motivate the requirements for future observations and prioritise processes that require improved understanding. Within our network we will hold a number of workshops to discuss a) existing data synthesis, b) model-observation comparisons, c) future data needs in the Eurasian boreal region, and d) plans for future aircraft field campaigns. In addition, we will make a scoping visit to the Central Aerological Observatory near Moscow, Russia, in order to evaluate the feasibility of different strategies for a joint aircraft campaign, considering issues such as logistics for joint operations and communication, geo-political constraints on aircraft operations, and experimental strategies for joint flying. The overall end-result of this project will be a coherent community of international scientists with a robust knowledge base of deficiencies in our understanding of short-lived climate pollutants, priorities for observations, and a strategy for developing future large-scale observation networks and large-scale field projects in the Eurasian boreal regions.
