Journal ArticleDOI
Origin of C2-C5 dicarboxylic acids in the European atmosphere inferred from year-round aerosol study conducted at a west-east transect
Michel Legrand,Susanne Preunkert,Tiago S. Oliveira,Casimiro Pio,Samuel Hammer,András Gelencsér,Anne Kasper-Giebl,Paolo Laj +7 more
TL;DR: An atmospheric study of C2-C5 dicarboxylic acids was conducted over two years at seven sites located from the Azores to eastern continental European sites as discussed by the authors.
Journal ArticleDOI

Journal ArticleDOI
Implication of weekly and diurnal 14C calibration on hourly estimates of CO‐based fossil fuel CO2 at a moderately polluted site in southwestern Germany
TL;DR: In this paper, a 7-year-long data set of integrated high-precision 14 CO 2 observations combined with occasional hourly CO 2 flask data from the Heidelberg sampling site is presented.
Journal ArticleDOI

Scheeren,Martin Steinbacher,Edward J. Dlugokencky +36 more
TL;DR: In this article, the authors present an ensemble of seven inverse models and performed four inversion experiments, investigating the impact of different sets of stations and the use of a priori information on emissions.
Journal ArticleDOI
Evaluation of aerosol sources at European high altitude background sites with trajectory statistical methods
Pedro Salvador,Begoña Artíñano,Casimiro Pio,Joana Afonso,Michel Legrand,Hans Puxbaum,Samuel Hammer +6 more
TL;DR: In this article, the influence of synoptic weather patterns and long-range transport episodes on the concentrations of several compounds related to different aerosol sources (EC, OC, SO42−, Ca2+, Na+, K+, 210Pb, levoglucosan and dicarboxylic acids) registered in PM10 or PM2.5 aerosol samples collected at three remote background sites in central Europe.
