Source apportionment of reactive nitrogen in fog vs. rain using isotope ratios and Bayesian modeling (Ore and Eagle Mts., Central Europe)
Original language description
Estimates of atmospheric inputs of reactive nitrogen (Nr) into ecosystems are often based on vertical deposition. We investigated to what extent horizontal deposition affects total atmospheric deposition of Nr in two sparsely populated mountain regions near the Czech–German–Polish borders in an era of easing pollution. Among three scenarios of horizontal-water contribution to rainfall (additional 5, 10 and 20%), the 10% scenario was considered the most realistic. Between 2023 and 2025, wet horizontal deposition of NH4+-N plus NO3--N constituted as much as 66–77% of total wet inorganic Nr deposition. Because condensation of rain and fog droplets occurs at different altitudes, we hypothesized that the Nr-source mix in horizontal and vertical deposition would differ. N-isotope analyses and Bayesian modeling indicated larger dominance (up to 75%) of vehicle-exhaust derived NH4+-N in fog than in rain. In contrast, the mix of NO3--N sources for fog and rain was nearly identical, with average contributions of six sources making up 9–24% each. Remote large NOx sources originating in coal-burning powerplants and natural-gas burning industries played similarly weak roles as more local and/or diffuse sources related to residential coal and wood burning, traffic and biogenic/soil emissions.
