项目摘要

The marine sulfur cycle is an exemplar of a climatically important biogeochemical cycle within the Earth system (initially described by the CLAW hypothesis). Marine sulfate aerosol produced from biogenic dimethyl sulfide (DMS) is the main component of natural aerosol over many oceanic regions and sets a baseline aerosol concentration against which the magnitude of anthropogenic aerosol radiative forcing is determined. However, recent discoveries of new sulfur molecules formed from DMS (e.g., HPMTF) force us to radically re-examine the role of marine sulfur in the climate system. The understanding embedded in current climate models is now significantly challenged by new aerosol formation pathways and by observations of marine emissions of other biogenic sulfur species that were previously dismissed as unimportant: What do these molecules do? How do the processes they participate in affect the natural sulfur cycle? How do these discoveries alter the impact of DMS emissions on climate and anthropogenically driven climate change? The recently discovered species and chemical pathways are not included in any Earth system models that inform global climate change policies through the IPCC, even though aerosols from natural sources are a key driver of uncertainty in radiative forcing. The significant gap in understanding of the natural sulfur cycle is a major limitation when trying to constrain the pre-industrial climate system, which is itself crucial for determining the allowed emissions of greenhouse gases needed to meet climate stabilisation targets.The CARES project will fill these holes in our knowledge of the marine atmospheric sulfur cycle through a combination of intensive aircraft and ship observations as well as multi-scale model experiments. Advancements in models, further informed by new laboratory data, will allow us to better understand contemporary and historical sulfur and climate observations. This will deliver a substantial revision to our understanding of the fate and impact of natural sulfur emissions. The results will be used to rectify errors in the representation of sulfur processes in Earth system models, constrain the role of marine sulfur in the Earth System, and improve confidence in simulations that project future change.
海洋硫循环是地球系统内气候上重要的地球化学循环的一个范例(最初由CLAW假说描述)。由生物源二甲基硫(DMS)产生的海洋硫酸盐气溶胶是许多海洋地区天然气溶胶的主要成分,并设定了基线气溶胶浓度,根据该浓度确定人为气溶胶辐射强迫的大小。然而,最近发现的由DMS形成的新硫分子(例如,HPMTF)迫使我们从根本上重新审视海洋硫在气候系统中的作用。嵌入在当前气候模型中的理解现在受到了新的气溶胶形成途径和以前被认为不重要的其他生物硫物种海洋排放的观测的重大挑战:这些分子做什么?它们参与的过程如何影响自然硫循环?这些发现如何改变二甲基硫醚排放对气候的影响以及由气候变化驱动的气候变化?最近发现的物种和化学途径没有被纳入任何通过IPCC为全球气候变化政策提供信息的地球系统模型中,尽管来自自然源的气溶胶是辐射强迫不确定性的关键驱动因素。在试图限制工业化前气候系统时,对自然硫循环的理解存在重大差距是一个主要限制,这本身对于确定满足气候稳定目标所需的温室气体允许排放量至关重要。CARES项目将通过密集的飞机和船舶观测以及多方面的观测,缩尺模型实验模型的进步,新的实验室数据的进一步通知,将使我们能够更好地了解当代和历史的硫和气候观测。这将大大改变我们对天然硫排放的命运和影响的理解。研究结果将用于纠正地球系统模型中硫过程表示的错误,限制海洋硫在地球系统中的作用,并提高预测未来变化的模拟的信心。
