Atmospheric Extinction at the Brno and Skalnaté Pleso Observatories. III. Model of extinction derived for Skalnaté Pleso from IHW/IAU medium-band photometrical observation of comets in 1985-90

Original language description

75 measurements of atmospheric extinction obtained during the observations of bright comets 1P/Halley in 1985/86, 23P/Brorsen-Metcalf in 1989 and C/Austin in 1990 in the IHW/IAU six-colour intermediate band photometric system at the Skalnaté Pleso Observatory have confirmed the validity of the two-component model of atmospheric extinction published in Paper II. That is a superposition of a more or less constant component of Rayleigh scattering on temporary clumps of molecules of air and a heavily variable component of scattering on dust particles (aerosols). The found value of spectral parameter a of the dust component of atmospheric extinction: alpha = 1.01+-0.28 suggests that the scattering centres are tiny dielectric dust particles. The results of IHW/IAU extinction study have been compared with the results of UBV extinction coefficients gained mostly as a by-product of the photoelectric photometry of variable stars (407 nights in the period from 1962 to 1995) on the Brno and Skalna
