“…Moreover, levoglucosan / K + ratios also can be influenced by combustion conditions, i.e., smoldering versus flaming burns. Biofuels are typically subject to smoldering combustion conditions in residential stoves for heating purposes in the rural areas in northern China, which was reflected in relatively higher levoglucosan / K + ratios than during flaming combustion (Schkolnik et al, 2005;Lee et al, 2010).…”

Abstract. Biomass burning activities are ubiquitous in China, especially in northern China, where there is a large rural population and winter heating custom. Biomass burning tracers (i.e., levoglucosan, mannosan and potassium (K+)), as well as other chemical components, were quantified at a rural site (Gucheng, GC) in northern China from 15 October to 30 November, during a transition heating season, when the field burning of agricultural residue was becoming intense. The measured daily average concentrations of levoglucosan, mannosan and K+ in PM2.5 (particulate matter with aerodynamic diameters less than 2.5 µm) during this study were 0.79 ± 0.75, 0.03 ± 0.03 and 1.52 ± 0.62 µg m−3, respectively. Carbonaceous components and biomass burning tracers showed higher levels during nighttime than daytime, while secondary inorganic ions were enhanced during daytime. An episode with high levels of biomass burning tracers was encountered at the end of October 2016, with high levoglucosan at 4.37 µg m−3. Based on the comparison of chemical components during different biomass burning pollution periods, it appeared that biomass combustion can obviously elevate carbonaceous component levels, whereas there was essentially no effect on secondary inorganic aerosols in the ambient air. Moreover, the levoglucosan / mannosan ratios during different biomass burning pollution periods remained at high values (in the range of 18.3–24.9); however, the levoglucosan / K+ ratio was significantly elevated during the intensive biomass burning pollution period (1.67) when air temperatures were decreasing, which was substantially higher than in other biomass burning periods (averaged at 0.47).

“…For other sites in Asia, even smaller differences are reported (Datta et al., 2012; Saraswati et al., 2018; Saylor et al., 2010; S. Wang et al., 2015). In addition, surface concentrations reported in the winter are often only just below those in April (e.g., Kuang et al., 2020; S. Wang et al., 2015). At night, mixing layers in the two months are also of comparable magnitude, and assuming that most NH 3 is located in the PBL, this implies that columns should be of similar magnitude too at night, what is consistent with what is observed here.…”

“…While NH 3 concentrations are expected to increase during daytime due to increased emissions and also evaporation of ammonium‐containing aerosols, the larger boundary layer prevents a large buildup of NH 3 near the surface. For example, in a rural site in the NCP, surface concentrations vary only between 25 and 40 ppb in April, with the maximum reached in the morning due to the evaporation of dew and guttation droplets (Kuang et al., 2020; Wentworth et al., 2016). For other sites in Asia, even smaller differences are reported (Datta et al., 2012; Saraswati et al., 2018; Saylor et al., 2010; S. Wang et al., 2015).…”

As the atmosphere's primary base and one of the main reactive nitrogen compounds, ammonia (NH 3 ) plays a key role in our atmosphere and the global nitrogen cycle (Fowler et al., 2013). Emitted in excess, NH 3 can lead to a dramatic loss of biodiversity and deterioration of water, soil and air quality (Bauer et al., 2016;Bobbink et al., 2010;Sutton, Bleeker, et al., 2013). Unlike other primary gaseous pollutants, such as the acidifying NO x and SO 2 (Aas et al., 2019;Georgoulias et al., 2019), concentrations of NH 3 are steadily increasing in large parts of the world (Sutton et al., 2020;Van Damme et al., 2021). NH 3 has stayed under the radar for long, partially as a result of the historic dearth of measurements. Fortunately, thanks to the availability of new and cheaper techniques, large measurement networks of ground-based stations are gradually put in place (Nair & Yu, 2020;Viatte et al., 2021). In addition, since over a decade, satellites equipped with high-resolution infrared spectrometers offer an unprecedented temporal and spatial sampling of the global NH 3 distributions, which has led to important progress in our understanding of its local to global emission and deposition fluxes and how these are evolving over time (e.g.,

“…This site is upwind of Beijing, when the wind blows from the south or southwest, where heavily polluted cities and regions of Hebei province, i.e., Baoding, Shijiazhuang, Xingtai, Handan, are located. Thus, it is an appropriate station for representing the air pollution situation in the NCP region (Sheng et al, 2018;Chi et al, 2018;Xu et al, 2019;Kuang et al, 2020).…”

Abstract. Biomass burning (BB) activities are ubiquitous in China, especially in North China, where there is an enormous rural population and winter heating custom. BB tracers (i.e., levoglucosan (LG), mannosan (MN) and potassium (K+)), as well as other chemical components were quantified at a rural site (Gucheng, GC) in North China from 15 October to 30 November, during a transition heating season, when the field burning of agricultural residues was becoming intense. The measured daily average concentrations of LG, MN and K+ in PM2.5 during this study were 0.79 ± 0.75 μg m−3, 0.03 ± 0.03 μg m−3 and 1.52 ± 0.62 μg m−3, respectively. Carbonaceous components and BB tracers showed higher levels at nighttime than daytime, while secondary inorganic ions were enhanced during daytime. An episode with high levels of BB tracers was encountered at the end of October, 2016, with high LG at 4.37 µg m−3. Based on the comparison of chemical components during different BB pollution periods, it appeared that biomass combustion can obviously elevate carbonaceous components levels, whereas no essentially effect on secondary inorganic aerosols in the ambient air. Moreover, the LG/MN ratios during different BB pollution periods remained at high values (in the range of 18.3–24.9), however, the LG / K+ ratio was significantly elevated during the intensive BB pollution period (1.67) when air temperatures decreasing, substantially higher than in other BB periods (averaged at 0.47).
