Abstract:

Preparations were made for the performance of a field experiment concerning the dispersion of fluorescent test aerosol particles within a mountain valley. Essentially they included the construction of 20 rotorod samplers and of 100 H-shaped vanes therefore. The samplers were improved by a new electronic circuit to ensure constant speed of the vanes even if battery voltage drops. A microscopical bench was installed for the counting of fluorescent particles in UV light. The aerosol generator was checked and test-run. The procedure for exact determination of air currents in the valley experiment using pilot balloons was further developed and respective computer programs set up. Preparatory work was done for installation of the aerosol generator on top of an isolated hill within the valley. Author
