Model calculations for the estimation of dry deposition of atmospheric trace substances. Final report. Modellrechnungen zur Bestimmung der trockenen Deposition atmosphaerischer Spurenstoffe. Abschlussbericht

Abstract

A numerical model will be demonstrated with which the deposition rate and deposition velocity of slowly reacting atmospheric trace elements can be determined using a detailed calculation of the turbulent flow. The process is so conceived that it only needs the profile data of the concentration and the meteorolgical field determinants in the turbulent phase of the air layer near to the ground. To determine the terminal conditions in the turbulent phase the so called K-theory is used, in the molecular turbulent lower layer a 'sublayer' STANTON number and the REYNOLDS analogy between the concentration distribution, the temperature profile and the wind velocity profile. Numerical examples, taken from the measurements from various field experiments are discussed. Using the NO-NO{sub 2}-O{sub 3} system as an example it will be shown how the process can also be used for reactive trace elements. (orig.) With 2 tabs., 11 figs., 37 refs.
