Occult precipitation as an important input to water and mass balance of the mountainous catchment
Tesař, Miroslav ; Šír, Miloslav ; Kulasová, A. ; Fottová, D. ; Eliáš, Václav
Present article deals with observation, assessment and modelling of the occult precipitation at the small representative basins in the National Park of the Šumava Mts. (Liz, 0,99 km2, 828 - 1024 m n.m.), National Park of Krkonoše (Giants) Mts. (Modrý potok, 2,62 km2, 1010 - 1554 m n.m.) and in the Protected Landscape Region of the Jizerské hory Mts.(Uhlířská, 1,87 km3, 780 - 870 m n.m.). The amount of occult precipitation was estimated with the use of the mathematical micrometeorological model and frog and cloud water samples collected with the help of passive and active collectors were chemically analysed.

Occult precipitation as an important contribution to the wet deposition in Bohemian Forest
Tesař, Miroslav ; Fottová, D. ; Eliáš, Václav ; Šír, Miloslav
Together six active fog-water collectors and ten passive fog-water collectors were installed in various suitably chosen mountainous parts and urban regions of the Czech Republic with different pollutants loads in order to evaluate if site-to-site differences exist. Fog deposition rates is calculated with the use of the Lovett's mathematical micrometeorogical and obtained samples of cloud were analysed for major ions. Estimated wet deposition for example for NH4+, NO3- and SO4-2 via fog and cloud droplets impaction and sedimentation represents 826, 1810 and 1900 kgkm-2 year-1, respectively.
