Evaluation of recently-proposed secondary organic aerosol models for a case study in Mexico City
Katja Džepina, Rainer Volkamer, Sasha Madronich, P. Tulet, I. M. Ulbrich, Qi Zhang, C. D. Cappa, P. J. Ziemann, Jose L. Jimenez
Izvirni znanstveni članek
Oznake: polycyclic aromatic-hydrocarbons;positive matrix factorization;mass-spectrometry;volatility measurements;
Recent field studies have found large discrepancies in the measured vs. modeled SOA mass loadings in both urban and regional polluted atmospheres. The reasons for these large differences are unclear. Here we revisit a case study of SOA formation in Mexico City described by Volkamer et al. (2006), du ...

Organic aerosol (OA) data acquired by the Aerosol Mass Spectrometer (AMS) in 37 field campaigns were deconvolved into hydrocarbon-like OA (HOA) and several types of oxygenated OA (OOA) components. HOA has been linked to primary combustion emissions (mainly from fossil fuel) and other primary sources ...

Development of a source-measurement instrument for lab-scale solar cells and mini-modules
Domen Banfi, Marko Jankovec, Carolin Ulbrich
Magistrsko delo
Oznake: fotovoltaika;metrologija;elektronika;sončna celica;inštrument;IU karakteristika;sledenje MPP;zaporna napetost;
V magistrskem delu se ukvarjamo z razvojem merilne naprave za testanje sončnih celic in mini-modulov v različnih delovnih točkah, namenjeno uporabi v zunanjih ali notranjih pogojih. Naloga naprave je, da nastavi izbrano napetost in izmeri tok in napetost na testirani celici ali mini-modulu. Naprava ...
