A study was conducted to measure aerosol hygroscopic properties at remote locations by using the Hygroscopicity Tandem Differential Mobility Analyzer (H-TDMA). The high-alpine site Jungfraujoch at 3580 m asl in Switzerland served as the study site. To ensure a constant temperature within the entire H-TDMA system, DMAs as well as the humidifier, were submersed in a water/ethylene glycol bath. The H-TDMA was tested with NaNO₃ aerosol generated by atomization of an aqueous solution. Measurements were performed at 20°C, 0.5°C and -11°C. Finally, a comparison was made between experimental and predicted theoretical data.
