Changes in the Fluorescence of Biological Particles Exposed to Environmental Conditions in the National Capitol Region

We examined the changes in the fluorescence spectra of bioaerosols when exposed to ambient outdoor conditions for periods of several hours. The bioaerosols in this study were contained in a chamber that allowed sunlight to penetrate, and an inner ePTFE membrane to allow ambient trace gasses to permeate the drums. The bioaerosols were periodically measured with a TSI UV-APS (excited at 355 nm) and a Single Particle Fluorescence Spectrometer (excited at 351 and 263 nm). Data deposited are, UV-APS data files, SPFS data files, solar intensity and environmental trace gas measurments.本研究探究了生物气溶胶（bioaerosols）在室外自然环境中暴露数小时过程中的荧光光谱变化规律。本研究中的生物气溶胶被存放于特制舱室内：该舱室可允许太阳光穿透，且内置ePTFE膜，使环境痕量气体可渗透进入舱体。研究人员定期采用TSI紫外气溶胶粒径谱仪（UV-APS，激发波长355 nm）与单粒子荧光光谱仪（Single Particle Fluorescence Spectrometer，SPFS，激发波长分别为351 nm和263 nm）对生物气溶胶进行检测。本次公开的数据集包含UV-APS数据文件、SPFS数据文件、太阳辐照度测量数据以及环境痕量气体测量数据。
