Abstract: Abstract. We present here a dynamical method for modelling temporal and geographical variations in ammonia emissions in regional-scale chemistry transport models (CTMs) and chemistry climate models (CCMs). The method is based on the meteorology in the models and gridded inventories. We use the dynamical method to investigate the spatiotemporal variability of ammonia emissions across part of Europe and study how these emissions are related to geographical and year-to-year variations in atmospheric temperature a… Show more

“…Although not all these linkages have yet been made, significant progress in the temporal distribution of NH 3 emissions according to agricultural activities has already been achieved, which can provide key input to the future developments [30,61,62]. For example, the US EPA Community Multiscale Air-Quality model includes coupling to an agro-ecosystem model to provide dynamic and meteorological-dependent emissions from fertilizer application, using a two-layer bidirectional resistance model based on Nemitz et al [15] that includes the effects of soil nitrification processes [18].…”

“…Agricultural emissions are related to farm buildings, manure, fertilisers, and grazing animals, and are strongly influenced by climate and weather [14]. NH 3 emissions varies primarily with temperature and air velocity [15].…”

“…On the eastern border there is more local production, which is entirely offset by less LRT. Averaging across simulations that adopt yearly-specific meteorological fields to gain a corresponding reduction term reveals that, with the exception of Vredepeel (131) Velders and Diederen, 2009;Walker et al, 2012;Xu and Penner, 2012;Skjøth and Geels, 2013;Hauglestaine et al, 2014). Our findings show that the methodology adopted for performing such studies can have an impact on the resulting conclusions related to projections of [NH þ 4 ] distribution and subsequent deposition in future decades.…”
