What is CHOPIN?  is a multi-part documentary about the the 2024-2025 CleanCloud CHOPIN (Cleancloud Helmos OrograPhic sIte experimeNt) campaign at Mt.Helmos, Greece: where mythology, aerosols, clouds and climate meet. This video is the fifth part, Act 5, focusing on the efforts to collect bioaerosols for studying their properties and ability to freeze water - and also the deployment of experimental sensing techniques to directly measure particle acidity - a critical but elusive property of particles - in the field. Apart from the sampling in the field, this Act also shows the "Enastron-Lab" (temporary laboratory setup in our hotel room) where samples are processed, preserved and the equipment is washed, disinfected and dried for next day's sampling.
