Abstract In-situ sampling with particle size spectrometers is an important method to provide detailed size spectra for atmospheric aerosol in the troposphere and stratosphere. Recently we developed a sensitive, light weight, and low cost optical particle spectrometer. The name of the instrument is Printed Optical Particle Spectrometer (POPS), where "Printed" stands for the fact that structural components where made with a 3D printer. Here we present the first scientific data recorded by POPS from an unmanned aircraft system (UAS) during the Soot Transport, Absorption and Deposition Study (STADS) campaign on Svalbard, Norway, in April 2015. As part of a payload composed of five different aerosol instruments - a photometer, condensation particle counter, a filter sampler, an upwards looking solar radiometer and POPS - we collected particle size distributions from 0 to 3000 m altitude using a Manta UAS. Furthermore, we present data from a stratospheric balloon flight out of Larimar, Wyoming. This study includes an inter comparison of POPS and other optical particle counters.
