Small particles in the stratosphere (10-30 km) affect the ozone layer that protects live from harmful ultraviolet solar radiation and also affect climate. These stratospheric aerosols are controlled by volcanic, natural and human activities that produce sulfur containing gases or particles. The US has the longest 40-year record of the vertical distribution of particles that has been made over Laramie, WY that has been invaluable to calibrate models and validate satellites. There is a prisoning need to continue this long-term record, modernize the instruments - making them better, lighter and cheaper and maintain US leadership in instrumentation and science. This proposal achieves this by developing a compact modern commercial sensor and mentoring a young PI to take over the leadership and transition operations to Boulder, CO.The project expands the long-term balloon borne measurements of stratospheric aerosols up to 30 km to build upon a unique 40-year record of profiles of aerosol concentration and size. The site will be transitioned from Laramie, WY to Boulder, CO and the plan includes the mentoring a new leader (currently co-PI). The instrument payload will be modernized by adapting a commercial optical particle counters (Lighthouse Remote 3104 clean room particle spectrometer) that will extend the capability and reduce size, weight and costs and enhance deployability. The aerosol profile is crucial for the understanding of long-term stratospheric aerosol-chemistry interactions, satellite retrievals and validation and troposphere-stratosphere coupling response to climate change. The project was re-scoped to focus on the design and validation of a next generation aerosol profiling system and build 2 prototypes and perform limited flight-testing and validation against current instrument. The project will also begin the transition of the activity to Boulder, CO including hardware and a new PI. The transition effort should result in competitive future science proposals and create long-term synergistic monitoring of balloon borne aerosol, trace-gas and water profile measurements for atmospheric chemistry, climate and satellite validation centered in Boulder, CO and assert US leadership.

平流层中的小颗粒（10-30 km）会影响保护生物免受有害紫外线辐射并影响气候的臭氧层。这些平流层气溶胶受到产生含有气体或颗粒的硫的火山，自然和人类活性的控制。美国拥有对Laramie的垂直分布最长的40年记录，WY对校准模型和验证卫星是无价的。囚禁需要继续这一长期记录，使乐器现代化 - 使它们变得更好，更轻松，更便宜，并保持我们在仪器和科学方面的领导地位。该提案通过开发紧凑的现代商业传感器并指导年轻的PI来接管Co. Boulder的领导和过渡操作来实现这一目标。该项目扩大了长期的气球阳离子的测量，对平流层气溶胶的测量最多30公里，以建立独特的40年气溶胶浓度和尺寸的40年记录。该网站将从怀俄明州的拉勒米（Laramie）过渡到科罗拉多州博尔德（Boulder），该计划包括指导新领导者（目前Co-Pi）。仪器有效载荷将通过调整商业光学粒子计数器（灯塔远程3104洁净室粒子光谱仪）来进行现代化，从而扩展功能并降低尺寸，重量和成本并增强可部署性。气溶胶曲线对于理解长期平流层气体化学相互作用，卫星检索和验证以及对流层 - 指示耦合响应对气候变化的响应至关重要。 该项目被重新分配为专注于下一代气溶胶分析系统的设计和验证，并构建2个原型，并对当前仪器进行有限的飞行测试和验证。该项目还将开始活动向Boulder，包括硬件和新PI，包括硬件。 过渡工作应导致未来的科学建议，并为大气化学，气候和卫星验证的气球传播，痕量气体和水剖面测量进行长期协同监控，并以CO，并主张我们的领导力。
