Aerosol Observing System (AOS): aerosol data, 1-min, mentor-QC applied - noaaaos

The aerosol observing system (AOS) is the primary platform for in situ aerosol measurements at Earth s surface. Each AOS has a different complement of instruments, which are selected to ensure the best measurements at each deployment site. \n \nThe AOS measures aerosol optical properties to better understand how particles interact with solar radiation and influence the Earth's radiation balance. These measurements are useful for calculating parameters used in radiative forcing calculations, such as the aerosol single scattering albedo, asymmetry parameter, mass scattering efficiency, and hygroscopic growth. Measurements made with the AOS form a long-term record at the ARM fixed sites. Shorter measurement records are available from mobile deployments in a wide variety of geographical regions. These measurements are valuable for: \n \n identifying long-term changes in aerosol properties \n identifying atmospheric processes controlling aerosol life cycle and their influence on clouds \n providing experimental data for developing and testing atmospheric climate models. \n

气溶胶观测系统（Aerosol Observing System，简称AOS）是开展地球地表原位气溶胶测量的核心平台。每套AOS配备的仪器组合各不相同，均会针对各部署场地的实际需求进行选型，以保障获取最优的测量结果。

AOS通过测量气溶胶光学特性，可深入解析气溶胶粒子与太阳辐射的相互作用机制及其对地球辐射平衡的影响。此类测量可用于计算辐射强迫计算所需的各类参数，包括气溶胶单次散射反照率（single scattering albedo）、不对称参数（asymmetry parameter）、质量散射效率（mass scattering efficiency）以及吸湿性增长（hygroscopic growth）。依托AOS开展的测量工作在ARM固定观测站点形成了长期观测数据集，而在各类地理区域开展的移动部署观测则可获取较短时长的测量记录。此类测量具有重要应用价值，具体包括：
- 识别气溶胶特性的长期演变趋势
- 解析调控气溶胶生命周期的大气过程及其对云系的影响
- 为大气气候模型的开发与验证提供实验观测数据。
