Abstract It is very important to measure atmospheric aerosols and analyze the characteristics of them since they have great effect on environment and human body. Satellite, aircraft, radio sonde have usually been used to measure vertical distribution of aerosols and its conditions such as temperature, humidity and atmospheric pressure. The common method of aircraft sampling takes that extracts collected particle on sampler filter and carries chemical analysis. Although, the method is favorable to measure the distribution of atmospheric aerosol, problems caused by fast flight speed; fragmentation of aerosol droplet and dispersion of collected particle, legal limit; flight altitude, prohibited airspace and flight time, and economical limit; frequency of sampling, have been restricted the measurement. These restrictions can be resolved by our all-in-one balloon system applying custom-made polyurethane balloon controlled by electrical winch. The system is composed of developed mini-impactor of 56g weight, several sensors, pump and its data processing board. It can not only collect atmospheric aerosol depending on each altitudes and particle sizes at low cost, but also monitor the atmospheric conditions; temperature, humidity, wind velocity, atmospheric pressure, GPS data, during the measurement.
In this research, we performed the atmospheric aerosol measurement using all-in-one balloon particle sampler system at altitude of 300m and 900m.
