Chemical characterization of atmospheric ions at the High-Alpine station Jungfraujoch (Switzerland)
<p>The ion composition at high-altitude (3454 m a.s.l.) was measured with an Atmospheric<br> Pressure interface Time of Flight mass spectrometer (APi-TOF) during a period of nine<br> months, from August 2013 to April 2014. The negative mass spectra were dominated by the<br> ions of sulfuric, nitric, malonic and methanesulfonic acid (MSA) as well as SO5- . The most<br> prominent positive ion peaks were from amines. The other cations were mainly organic compounds<br> clustered with a nitrogen-containing ion, which could be either NH4+ or an aminium.<br> Occasionally the positive spectra were characterized by groups of compounds each differing<br> by a methylene group. In the negative spectrum, sulfuric acid was always observed during<br> clear sky conditions following the diurnal cycle of sun irradiation. On many occasions we<br> also saw a high signal of sulfuric acid during night time when clusters up to the tetramer<br> were observed. A plausible reason for these events could be evaporation from particles at low<br> relative humidity. A remarkably strong correlation between the signals of SO5- and CH3SO3-<br> was observed for the full measurement period. The presence of these two ions during both<br> the day and the night suggests a non-photochemical channel of formation which is possibly<br> linked to halogen chemistry. Halogenated species, especially Br– and IO3- , were frequently<br> observed in air masses that originated mainly from the Atlantic Ocean and occasionally from<br> continental areas based on back trajectory analyses. We found I2O5 clustered with an ion, a<br> species that was proposed from laboratory and modelling studies. All halogenated ions exhibited<br> an unexpected diurnal behaviour with low values during day time. New particle formation<br> (NPF) events were observed and characterized by 1) highly oxygenated molecules (HOMs) and<br> low sulfuric acid or 2) ammonia-sulfuric acid clusters. We present characteristic spectra for<br> each of these two event types based on 26 nucleation episodes. The mass spectrum of the<br> ammonia-sulfuric acid nucleation event compares very well with laboratory measurements<br> reported from the CLOUD chamber. A source receptor analysis indicates that new particle<br> formation events at the Jungfraujoch take place within a restricted period of time of 24-48<br> hours after air masses have had contact with boundary layer. This time frame appears to be<br> crucial to reach an optimal oxidation state and concentration of organic molecules necessary<br> to facilitate nucleation.</p>

Data from: Paleolimnological assessment of wildfire-derived atmospheric deposition of trace metal(loid)s and major ions to subarctic lakes (Northwest Territories, Canada)
<p>Wildfires release terrestrial elements to the atmosphere as aerosols, and these events are becoming more frequent and intense in the Arctic boreal forest as the climate is warming. We quantified the impact of atmospheric deposition of aerosols from local wildfires on metal(loid) fluxes using macroscopic charcoal accumulation rates, historical fire mapping, and element concentrations in <sup>210</sup>Pb‐dated lake sediment from five subarctic lakes with small catchments. Lake sediments showed small but significant increases in fluxes (median = 5–10%) for 22 trace metals, metalloids, or major ions following fire events. The impact of wildfire aerosols on element fluxes was mostly due to short‐term (≤2 years) increasing sedimentation rate (6 ± 41% increase), whereas sediment element concentrations were not strongly impacted. Wildfire‐associated deposition to lake sediments was mainly composed of Ca, Al, Fe, Mg, K, Mn, and Na, which are major constituents of ash from burned biomass, but changes in sediment flux were greatest for Sb, As, Ni, Ba, Mn, Mo, and Sr compared to pre‐disturbance conditions. Compared to anthropogenic sources of pollution, wildfire‐associated atmospheric fluxes of metal contaminants to the lakes (e.g., Hg, Pb, As, Sb, and Cd) were low. This study provides quantitative estimates of wildfire impacts on atmospheric geochemical fluxes to subarctic lakes, which can be used for modeling larger‐scale impacts under changing fire regimes.</p>
