Recent technological advances have allowed the development of robust, relatively compact, low power, rapid response (approximately 1 s) instruments with sufficient sensitivity and specificity to quantify many trace gases and aerosol particle components in the ambient atmosphere. Suites of such instruments can be deployed on mobile platforms to study atmospheric processes, map concentration distributions of atmospheric pollutants, and determine the composition and intensities of emission sources. A mobile laboratory containing innovative tunable infrared laser differential absorption spectroscopy (TILDAS) instruments to measure selected trace gas concentrations at sub parts-per-billion levels and an aerosol mass spectrometer (AMS) to measure size resolved distributions of the nonrefractory chemical components of fine airborne particles as well as selected commercial fast response instruments and position/velocity sensors is described. Examples of the range of measurement strategies that can be undertaken using this mobile laboratory are discussed, and samples of measurement data are presented.
最近的技术进步使得能够开发出强大、相对紧凑、低功耗、快速响应（约1秒）的仪器，这些仪器具有足够的灵敏度和特异性，可对环境大气中的许多痕量气体和气溶胶颗粒成分进行量化。这类仪器套件可部署在移动平台上，用于研究大气过程、绘制大气污染物浓度分布图以及确定排放源的组成和强度。本文描述了一个移动实验室，其中包含用于测量十亿分比以下选定痕量气体浓度的创新型可调谐红外激光差分吸收光谱仪（TILDAS）以及用于测量空气中细颗粒非难熔化学成分的粒径分辨分布的气溶胶质谱仪（AMS），还有选定的商用快速响应仪器和位置/速度传感器。讨论了使用该移动实验室可采用的一系列测量策略示例，并展示了测量数据样本。
