Abstract

Accurate representation of atmospheric aerosol properties is a long-standing problem in atmospheric research. Modern pilotless aerial systems provide a new platform for atmospheric in situ measurement. However, small airborne platforms require miniaturized instrumentation due to apparent size, power, and weight limitations. A Portable Optical Particle Spectrometer (POPS) is an emerged instrument to measure ambient aerosol size distribution with high time and size resolution, designed for deployment on a small unmanned aerial system (UAS) or tethered balloon system (TBS) platforms. This study evaluates the performance of a POPS with an upgraded laser heater and additional temperature sensors in the aerosol pathway. POPS maintains its performance under different environmental conditions as long as the laser temperature remains above 25 °C and the aerosol flow temperature inside the optical chamber is 15 °C higher than the ambient temperature. The comparison between POPS and an Ultra-High Sensitivity Aerosol Spectrometer (UHSAS) suggests that the coincidence error is less than 25% when the number concentration is less than 4000 cm. The size distributions measured by both of them remained unaffected up to 15,000 cm. While both instruments' sizing accuracy is affected by the aerosol chemical composition and morphology, the influence is more profound on the POPS.

摘要

准确表征大气气溶胶特性是大气研究中一个长期存在的问题。现代无人驾驶航空系统为大气原位测量提供了一个新平台。然而，由于明显的尺寸、功率和重量限制，小型机载平台需要小型化仪器。便携式光学粒子光谱仪（POPS）是一种新出现的仪器，用于以高时间和尺寸分辨率测量环境气溶胶尺寸分布，设计用于部署在小型无人机系统（UAS）或系留气球系统（TBS）平台上。本研究评估了一台在气溶胶通道中配备升级激光加热器和额外温度传感器的POPS的性能。只要激光温度保持在25°C以上且光学腔内的气溶胶流温度比环境温度高15°C，POPS就能在不同环境条件下保持其性能。POPS与超高灵敏度气溶胶光谱仪（UHSAS）之间的比较表明，当数浓度小于4000 cm⁻³时，重合误差小于25%。它们测量的尺寸分布在高达15000 cm⁻³时都不受影响。虽然两种仪器的尺寸测量精度都受气溶胶化学成分和形态的影响，但对POPS的影响更为显著。
