Opis: Aerosols play an important yet uncertain role in modulating the radiation balance of the sensitive Arctic atmosphere. Organic aerosol is one of the most abundant, yet least understood, fractions of the Arctic aerosol mass. Here we use data from eight observatories that represent the entire Arctic to reveal the annual cycles in anthropogenic and biogenic sources of organic aerosol. We show that during winter, the organic aerosol in the Arctic is dominated by anthropogenic emissions, mainly from Eurasia, which consist of both direct combustion emissions and long-range transported, aged pollution. In summer, the decreasing anthropogenic pollution is replaced by natural emissions. These include marine secondary, biogenic secondary and primary biological emissions, which have the potential to be important to Arctic climate by modifying the cloud condensation nuclei properties and acting as ice-nucleating particles. Their source strength or atmospheric processing is sensitive to nutrient availability, solar radiation, temperature and snow cover. Our results provide a comprehensive understanding of the current pan-Arctic organic aerosol, which can be used to support modelling efforts that aim to quantify the climate impacts of emissions in this sensitive region.

Secondary organic aerosol formation from semi- and intermediate-volatility organic compounds and glyoxal : relevance of O/C as a tracer for aqueous multiphase chemistry
Eleanor M. Waxman, Katja Džepina, Barbara Ervens, Julia Lee-Taylor, Bernard Aumont, Jose L. Jimenez, Sasha Madronich, Rainer Volkamer, 2013, izvirni znanstveni članek

Opis: The role of aqueous multiphase chemistry in the formation of secondary organic aerosol (SOA) remains difficult to quantify. We investigate it here by testing the rapid formation of moderate oxygen-to-carbon (O/C) SOA during a case study in Mexico City. A novel laboratory-based glyoxal-SOA mechanism is applied to the field data, and explains why less gas-phase glyoxal mass is observed than predicted. Furthermore, we compare an explicit gas-phase chemical mechanism for SOA formation from semi- and intermediate-volatility organic compounds (S/IVOCs) with empirical parameterizations of S/IVOC aging. The mechanism representing our current understanding of chemical kinetics of S/IVOC oxidation combined with traditional SOA sources and mixing of background SOA underestimates the observed O/C by a factor of two at noon. Inclusion of glyoxal-SOA with O/C of 1.5 brings O/C predictions within measurement uncertainty, suggesting that field observations can be reconciled on reasonable time scales using laboratory-based empirical relationships for aqueous chemistry.

Slovenska literatura med špansko govorečimi
Polona Konjedic, Barbara Pregelj, Julia Sarachu, Barbara Vuga, Susana Aliano Casales, Moisés Selfa Sastre, 2020, druge monografije in druga zaključena dela

Opis: Kako poznajo slovensko literaturo v Mehiki? O kom se učijo bodoči učitelji v Lleidi? Kaj slovenskega poznano v Urugvaju, o kom od slovenskih avtorjev predavajo na Univerzi v Buenos Airesu? Odgovore na ta vprašanja imajo Julia Sarachu, Barbara Vuga, Susana Aliano Casales, Moisés Selfa Sastre in Barbara Pregelj. Z njimi se je pogovarjala Polona Konjedic.
