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.

该提案旨在首次开发和部署轻型低成本（一次性）多物种化学探空仪，以解决对流层和平流层成分测量能力的限制。探空仪将采用申请人开发的最先进的 CO、O3 和 CO2 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）。目的是使探空仪适用于 SHADOZ 和 GRUAN 等全球探空仪网络以及独立使用，适用于短期案例研究（例如运输、化学过程）和长期监测（例如与趋势检测和气候变化相关）。该项目将分为四个阶段：- 开发和建设：涉及将化学传感器集成到传感器模块及其与现有维萨拉的接口 RS92 和新的 RS41 无线电探空仪系统。- 测试和验证：将在 JOSIE 大气模拟室中进行，与传统臭氧探空仪同时飞行，并与 NERC FAAM 研究飞机同时飞行。 - 现场部署：a) 作为更大规模测量活动一部分的密集现场活动，以及 b) 12-18 个月的定期测量。这些部署将在马来西亚进行，并将用于热带大气的研究。-数据分析：成分概况的统计分析以及与 NAME 和 UKCA 模型的比较，以研究热带对流层顶层 (TTL) 的化学和传输过程以及东南亚上空自由对流层中成分的传输。我们与项目合作伙伴一起拥有开发和证明这些新成分探空仪的专业知识和知识。通过由业务气象机构以最少的基础设施定期启动，有可能彻底改变大气测量计划。
