During an international comparison workshop at the 'World Calibration Center for Aerosol Physics (WCCAP)' in Leipzig, two portable mobility spectrometers were investigated with respect to their accuracy for measuring the number concentration of ultrafine particles as well as the particle size distribution. The results were recently published in the discussion forum of the journal Atmospheric Measurement Techniques (https://amt.copernicus.org/preprints/amt-2022-155/).
