Scope of project
Within this project, PSI will conduct airborne measurements on board of a Zeppelin and ground based mobile measurements with the PSI mobile laboratory. Intensive measurements are planned in 2012 and 2013 and will be conducted in the Po-Valley, Mid-west Europe, and Northern Europe. In addition, specific smog chamber experiments will be done at PSI for comparison with the field observations.
Currently, a white light humidified optical particle spectrometer (WHOPS) is developed for the employment on board of a Zeppelin. The WHOPS is a complementary instrument to the HTDMA and humidified nephelometer as it delivers size segregated information on the particles hygroscopic growth and refractive index.
The following questions will be addressed:
- What are the aerosol hygroscopic properties and vertical profiles in the planetary boundary layer?
- What are the relevant aerosol aging processes?
