项目摘要

This proposal is to develop and deploy for the first time lightweight low cost (disposable) multi-species chemical sondes to address limitations in composition measurement capability in the troposphere and low stratosphere. The sondes would incorporate state of the art CO, O3 and CO2 sensors developed by the applicants, and would be launched on standard meteorological balloons flown by National Weather Services (thus providing T, P, RH). The intention is that the sonde be suitable for use in global sonde networks such as SHADOZ and GRUAN as well as for stand-alone use, with applicability to both short term case studies (e.g. transport, chemical processes) and long term monitoring (for example linked to trend detection and climate change).The project will be in four phases:- Development and construction: involving integration of chemical sensors into a sensor module and its interface with the existing Vaisala RS92 and the new RS41 radiosonde systems.- Testing and validation: to be carried out in the JOSIE atmospheric simulation chamber, on simultaneous flights with conventional ozone sondes and in parallel with flights by the NERC FAAM research aircraft. - Field deployment: to be conducted as a) an intensive field activity as part of a larger measurement campaign, and b) regular measurement for 12-18 months. These deployments will be in Malaysia and will be used in studies of the tropical atmosphere.- Data analysis: statistical analysis of composition profiles and comparisons with the NAME and UKCA models to study chemical and transport processes in the tropical tropopause layer (TTL) and the transport of constituents in the free troposphere over Southeast Asia.We have, together with our project partners, the expertise and knowledge to develop and prove these new composition sondes which have the potential to revolutionise atmospheric measurement programmes through their ability to be launched routinely by operational meteorological agencies with minimum infrastructure.

这项提议是首次开发和部署轻型、低成本(一次性)多组分化学探测仪，以解决对流层和低平流层在成分测量能力方面的限制。探测仪将包括由申请者开发的最先进的一氧化碳、臭氧和二氧化碳传感器，并将在国家气象局飞行的标准气象气球上发射(从而提供T、P、RH)。其目的是使该探测仪既适用于SHADOZ和Gruan等全球探测网，也适用于独立使用，既适用于短期案例研究(例如运输、化学过程)，也适用于长期监测(例如与趋势探测和气候变化有关)。该项目将分四个阶段进行：-开发和建造：将化学传感器集成到传感器模块及其与现有的Vaisala RS92和新的RS41无线电探空仪系统的接口。-测试和验证：将在Josie大气模拟舱中进行，在使用常规臭氧探测仪的同时飞行，以及与NERC FAAM研究飞机的飞行并行。-外地部署：a)作为更大的测量活动的一部分进行密集的实地活动，b)12-18个月的定期测量。这些部署将在马来西亚进行，并将用于研究热带大气。-数据分析：成分分布的统计分析，并与NAME和UKCA模型进行比较，以研究热带对流层顶层(TTL)的化学和输送过程，以及东南亚自由对流层中的成分输送。我们与我们的项目合作伙伴一起，拥有专门知识和知识来开发和证明这些新的合成探测仪，这些探测仪有可能通过它们的能力而带来大气测量计划的革命性变化，这些探测仪能够由基础设施最少的气象业务机构常规发射。
