A High-Sensitivity Low-Cost Optical Particle Counter Design

few particle sensors suitable for balloon deployment have been described in the literature (Hofmann et al. 1975; Hayashi et al. 1998; Sugita et al. 1999; Deshler et al. 2003; Kasai et al. 2003; Iwasaki et al. 2007; Hill et al. 2008). Most of these sensors are not capable of measuring particles below 150-nm diam-eter and/or are not suitable for disposable sondes. Since the aerosol accumulation mode in remote …
