Short summary
Aerosol particles are an important component of the Earth's atmosphere. Here we describe the composition and characterization of a new optical particle size spectrometer (OPSS) for aircraft-borne measurements of the aerosol particle size distribution (how many particles there are with a certain size) in the 140–1050 nm size range. The OPSS was characterized throughout concerning its measurement capabilities (response, pressure dependence, coincidence) and validated versus balloon measurement.
