Towards a better spatial quantification of nitrogen deposition: A case study for Czech forests

Comparison of Methods for the Estimation of Total Inorganic Nitrogen Deposition to Forests in Germany

“…Previous reviews of deposition velocities for different forest types and substances reported a large variability of vd values, which appeared to be sensitive to several parameters such as receptor surface properties, meteorological conditions as well as seasonal, and diurnal variations (Hunová et al, 2016). To account for this variability, we derived two sets of deposition velocities.…”

“…Unlike WD, which is fairly easy to assess (Staelens et al, 2008;Dämmgen et al, 2013), the quantification of ID is much more challenging. As OD is often of orographic origin, it usually only contributes significantly to TD in mountainous regions (Kirchner et al, 2014;Hunová et al, 2016).…”

Ambient Air Quality in the Czech Republic: Past and Present

“…Similarly as in other regions of Europe and US [194,195], it was demonstrated that in the CR, by not considering (1) deposition path via fog and (2) unmeasured constituents of dry deposition, such as NH 3 and HNO 3 (g), the total sulphur and nitrogen depositions are likely to be underestimated substantially [196,197]. Although the chemistry of fog is regularly observed at only a few sites in the CR, and information on fog chemistry is scarce [198,199], it is widely recognised that fog in the CR is enriched as compared to rain, particularly in SO 4 2-and NO 3 - [103,104,200].…”

Nitrogen deposition and its impact on forest ecosystems in the Czech Republic - change in soil chemistry and ground vegetation

“…The N deposition is likely to be substantially underestimated not accounting for several important non-measured compounds, such as NH3 and HNO3 (g), and contribution of occult deposition, as recently shown by Hůnová et al (2016).…”
