Abstract Unmanned aerial systems (UAS) are significantly expanding observational perspectives in atmospheric science. With rapid growth in the variety of both platform and UAS applications, the opportunity for these platforms to provide high-quality atmospheric measurements continues to expand. The measurements provided by various platforms are essential for contributing scientifically significant datasets. However, limited aerosol UAS instruments are available, due to the weight, size and power constrains in UAS. The information about miniaturized instrument performance, characterization, and especially the compatibility with their sibling version used in aircraft are very rare.
This work focuses on characterization of miniaturized aerosol spectrometer-printed optical particle spectrometer (POPS, Handix Inc.) in Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF). The operation of POPS compared with aircraft version – Passive Cavity Aerosol Spectrometer Probe (PCASP, DMT) were performed. In addition, two POPS are deployed to the Inaugural Campaigns for ARM Research using Unmanned Systems (ICARUS) field campaign, and the aerosol number concentration and size distribution from Oliktok Point, Alaska will be discussed.
