| Description | The behaviour of atmosperic extinction at the Skalnate Pleso Observatory can be satisfactorily described by a standard two-component model consisting of more or less constant component given namely by the Rayleigh scattering and a variable one caused by a scattering of light on dust particles. In order to explain properties of Brno extincion we introduce an additional, variable "particular extinction" acting mainly in U and B colours. Long-term and seasonal variations of both variable components of extinction in the B colour have been thoroughly investigated. The proposed extinction models are confronted with observations in all colours of UBV system. Trends of the UBVRI extinctions are discussed. |
