Abstract Aerosol vertical/horizontal distribution within the air boundary layer, though it is an important parameter for receptor or dispersal aerosol source models, is rather than directly determined calculated from earthbound measurements. To conduct airborne aerosol measurements, we constructed gondola attached to the airship. The airship, about 9m long and 2.5m height, was able to carry experimental cargo about 7 kg. There were three instruments for aerosol parameter determination accommodated in the gondola and connected to the inlets preheated to 50 Celsius degrees. Parameters determined were PM10, PM2.5 and PM1 and aerosol particle number concentrations of fine and ultrafine particles. Both the airship position and the aerosol data were acquired with frequency of 1Hz. Since the airship velocity ranges from 3 to 8 metres per second, highly spatial-temporal data for the aerosol mass/number were retrieved. Measurements were conducted above a large coal strip mine and in an urban air in winter 2012/2013. This work was partially supported by the project CENATOX under grant GAČR P503/12/G147.
