CO2MVS Research on Supplementary Observations

为了支持欧盟国家评估其在实现《巴黎协定》中商定的目标方面的进展情况，欧盟委员会明确表示，需要一种客观的方式来监测人为二氧化碳排放。这种能力将提供一致和可靠的信息，以支持政策和决策进程。为了保持欧洲在这一领域的独立性，欧盟必须建立一个以观测为基础的人为二氧化碳排放监测和核查支助能力，作为其哥白尼方案的一部分。H2020项目CHE和COCO2已经开始扩大CO2MVS原型系统，因此可以在哥白尼大气监测服务(CAMS)内实施，目标是到2026年投入使用。Corso项目将进一步支持建立新的CO2MVS，以解决具体的研发问题。CORSO将在全球和当地范围内提供能力，利用对伴生物种的观测，利用其排放比率和不确定性，更好地估计人为二氧化碳排放。CORSO还将评估全球和区域尺度反演中高时间分辨率现场14CO2和APO观测的附加值，以及全球CO2MVS系统中土壤水分、LAI、SIF和生物量的卫星观测的附加值，以更好地区分化石燃料和生物圈通量对大气二氧化碳浓度的影响。CORSO的主要长期影响将来自于提供记录在案的方法、原型系统和建议，解决上述确定的主题，为CO2MVS业务能力的提升提供支持，从而确保更全面和准确的CAMS人为二氧化碳排放监测和核查支持能力。

To support EU countries in assessing their progress for reaching their targets agreed in the Paris Agreement, the European Commission has clearly stated that an objective way to monitor anthropogenic CO2 emissions is needed. Such a capacity will deliver consistent and reliable information to support policy- and decision-making processes. To maintain Europe’s independence in this domain, it is imperative that the EU establishes an observation-based operational anthropogenic CO2 emissions Monitoring and Verification Support (CO2MVS) capacity as part of its Copernicus programme. The H2020 projects CHE and CoCO2 have already started the rampingup of the CO2MVS prototype systems, so it can be implemented within the Copernicus Atmosphere Monitoring Service (CAMS) with the aim to be operational by 2026. The CORSO project will further support establishing the new CO2MVS addressing specific research & development questions. CORSO will deliver the capabilities at global and local scale to optimally use observations of comitted species using their emission ratios and uncertainties to better estimate anthropogenic CO2 emissions. CORSO will also assess the added-value of high-temporal resolution in-situ 14CO2 and APO observations in global and regional scale inversions and of satellite observations of soil moisture, LAI, SIF, and Biomass in the global CO2MVS system to better separate the impact of fossil fuel and biospheric fluxes on the atmospheric CO2 concentrations. The main long-term impact of CORSO will come through the delivery of documented methodologies, prototype systems, and recommendations, addressing the identified topics above, feeding into the rampingup of the operational CO2MVS capacity and therefore ensuring a more comprehensive and accurate CAMS anthropogenic CO2 emission monitoring and verification support capacity.
