The DUSTER (Dust in the Upper Stratosphere Tracking Experiment and Retrieval) project is aimed at uncontaminated collection and retrieval of stratospheric solid aerosol particles, in the submicron/micron range, from the upper stratosphere. The approach implies: (1) in-situ particles collection; (2) sample recovering; and (3) laboratory analyses. The scientific aim is deriving the dust size distribution, the concentration, chemistry and mineralogy of the collected stratospheric aerosols. The main characteristics of the instru- ment are: (1) Capability of working autonomously during balloon flight at 30 − 40 km altitude, temperatures down to −80◦C; (2) sampling at least 20 m3 of air to collect several hundreds of aerosol particles); (3) Samples storage and retrieval under controlled condi- tions. A detailed description of the experiment is reported here
