The objective of this project was to investigate the limits of nephelometers regarding aerosol size.

I owe a big thank you to Dr. Martin Gysel-Beer and Qizhi Xu from PSI's Aerosol Physics and Optics Group for accompanying me through this project, they were immensely helpful and supportive! Also, I would like to thank Prof. Dr. Ulrike Lohmann for overseeing the project at ETH.
