项目摘要

With the adoption of the Paris climate agreement in December 2015, 197 countries have agreed to act to limit the growth in greenhouse gas (GHG) emissions and. As part of this agreement, these countries will provide enhanced transparency in their greenhouse gas emission reporting. An important element of this will be to ensure that there is independent confirmation that signatories are meeting their obligations.It is widely recognised therefore that monitoring GHGs in the atmosphere is needed to underpin verification methods which can provide critical confirmatory evidence of compliance. Cities, where a majority of human-caused greenhouse gases originate, are ideal testing grounds for different emissions verification methods. For example, multi-million dollar "megacities" projects have recently been developed and deployed in cities such as Los Angeles and Indianapolis, in these cases with emissions being verified using combinations of surface, aircraft-based and space-based instrumentation. Those projects are ground-breaking and have been successful, particularly in engaging local communities and policy makers in the global climate debate. However, the expense and complexity of these multi-platform projects severely limit the scope for rolling out similar efforts across the necessary hundreds of major cities, particularly in the developing world. Furthermore, it is important to rigorously quantify (as well as reduce) the uncertainties in emissions if this information is to be transparent and policy-relevant. Therefore, in this proposal we set out the following objectives:1: Adapt and deploy new low cost sensor network technologies to measure CO2, CO and CH4 at precisions and accuracies appropriate for accurate urban-scale emissions evaluation.2: Develop a high-resolution trace gas "inverse" method for estimating emissions using atmospheric measurements, which quantifies uncertainties more exhaustively than previous studies.3: Undertake a case study for the first high-resolution emissions evaluation of CO2, and CH4 in and around London using a network of 20 new-generation, autonomous sensor packages.Recent developments in low cost optical sensors for carbon dioxide (CO2) and methane (CH4) provide the basis for trace level sensor networks for these important greenhouse gases. This proposal is to couple these sensors with recent developments in low cost sensor network calibration and assimilation methodologies to create a GHG emission monitoring network system across London. The observations will be interpreted using state of the art inversion methodologies applied to a combined urban dispersion and atmospheric transport models. We will combine this sensor network with observations from the UK DECC/BEIS network, the Royal Holloway University of London monitoring site, and satellite instruments to produce a integrated comprehensive high-resolution picture of London's GHG emissions.This project brings together world-leading teams in sensor network technologies and emissions estimation techniques, along with a team of actively engaged stakeholders. The main deliverables are:- The creation and validation of a low cost GHG sensor network emissions methodology- The optimisation and deployment of a dense sensor network for GHG monitoring and source attribution across London. - CO2 and CH4 emissions estimates for Greater London for a 12 month period.London is the main focus of this proposal, however, the overarching aim is to develop and validate a methodology that would have wider applicability, both to other geographic locations and magacities and the extension to other GHGs (e.g. N2O) when suitable sensors become available. In doing so we would provide a tool both to inform GHG mitigation policy and, in the longer term, to provide improved evaluation of expected GHG reductions on the regional scales and below.
随着2015年12月巴黎气候协议的通过,197个国家同意采取行动限制温室气体(GHG)排放的增长。作为这项协议的一部分,这些国家将提高其温室气体排放报告的透明度。这项工作的一个重要内容将是确保对签署国履行义务的独立确认。因此,人们普遍认识到,需要监测大气中的温室气体,以支持能够提供关键的履约确认性证据的核查方法。城市是人类造成的温室气体的主要来源,是不同排放验证方法的理想试验场。例如,最近在洛杉矶和印第安纳波利斯等城市开发和部署了耗资数百万美元的“特大城市”项目,在这些项目中,使用地面、飞机和天基仪器的组合来核实排放。这些项目具有开创性,并取得了成功,特别是在让当地社区和政策制定者参与全球气候辩论方面。然而,这些多平台项目的费用和复杂性严重限制了在必要的数百个大城市开展类似努力的范围,特别是在发展中国家。此外,如果这些信息要透明并与政策相关,那么严格量化(以及减少)排放中的不确定性是很重要的。因此,在这项提议中,我们提出了以下目标:1:采用和部署新的低成本传感器网络技术,以与准确的城市规模排放评估相适应的精确度和精确度测量二氧化碳、CO和CH4。2:开发一种使用大气测量来估计排放的高分辨率痕量气体“逆”方法,该方法比以前的研究更详尽地量化不确定性。3:利用20个新一代的网络,对伦敦及其周围地区的二氧化碳和CH4进行首次高分辨率排放评估的案例研究。自主传感器组件。低成本二氧化碳(CO2)和甲烷(CH4)光学传感器的最新发展为这些重要温室气体的痕量水平传感器网络提供了基础。这项提议是将这些传感器与低成本传感器网络校准和同化方法的最新发展相结合,以创建一个遍及伦敦的温室气体排放监测网络系统。这些观测结果将使用最先进的反演方法进行解释,这些方法适用于城市弥散和大气传输的组合模型。我们将把这个传感器网络与英国DECC/BEIS网络、伦敦皇家霍洛威大学监测点和卫星仪器的观测结果结合起来,生成一张完整的高分辨率伦敦温室气体排放综合图片。这个项目汇集了传感器网络技术和排放估计技术方面的世界领先团队,以及一个积极参与的利益相关者团队。主要成果是:-创建和验证低成本的温室气体传感器网络排放方法--优化和部署密集的传感器网络,用于整个伦敦的温室气体监测和来源归属。-大伦敦地区12个月的二氧化碳和甲烷排放量估计。伦敦是这项建议的主要重点,但总体目标是开发和验证一种方法,该方法将具有更广泛的适用性,既适用于其他地理位置和地区,也适用于其他温室气体(如N2O),当有合适的传感器可用时。通过这样做,我们将提供一种工具,既为温室气体缓解政策提供信息,又从长远来看,改进对区域范围及以下温室气体预期减排量的评估。
