Concentration levels of cellulose (biannual averages) range from 16.3 ng\/m<jats:sup>3<\/jats:sup> at the oceanic background site AZO (Azores) to 181 ng\/m<jats:sup>3<\/jats:sup> at KPZ (Hungary). Concentrations decrease with elevation, winter levels at the midtropospheric Sonnblick site (SBO, 3106 m) are comparable to clean Atlantic conditions. The atmospheric concentration of plant debris (biannual averages) was derived from the cellulose data and ranges from 33.4 ng\/m<jats:sup>3<\/jats:sup> at AZO to 363 ng\/m<jats:sup>3<\/jats:sup> at KPZ. Relative contributions of plant debris to organic matter (OM) range from around 2% at the semirural coastal site Aveiro (AVE) to 10% at SBO. Surprisingly high relative concentrations of plant debris in OM were observed for wintry conditions at the elevated sites. The relative fraction of plant debris in OM ranged as averages from 6.1% at Schauinsland, Germany (1205 m) to 10.1% at Puy de Dome, France (1405 m) and 22.4% at Sonnblick, Austria (3106 m). Thus plant debris is a very important constituent of the organic material at elevated background sites with summer concentrations of around 5% and winter levels from around 6\u201322% depending on elevation. Since cellulose is considered rather long\u2010lived with respect to atmospheric oxidation processes, it may become enriched on the way to background regions, which may explain the elevated relative levels at elevated sites.<\/jats:p>","DOI":"10.1029\/2006jd008180","type":"journal-article","created":{"date-parts":[[2007,8,13]],"date-time":"2007-08-13T20:12:33Z","timestamp":1187035953000},"source":"Crossref","is-referenced-by-count":37,"title":["Concentration of atmospheric cellulose: A proxy for plant debris across a west\u2010east transect over Europe"],"prefix":"10.1029","volume":"112","author":[{"given":"Asunci\u00f3n","family":"S\u00e1nchez\u2010Ochoa","sequence":"first","affiliation":[{"name":"Institute for Chemical Technologies and Analytics Vienna University of Technology  Vienna Austria"}]},{"given":"Anne","family":"Kasper\u2010Giebl","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technologies and Analytics Vienna University of Technology  Vienna Austria"}]},{"given":"Hans","family":"Puxbaum","sequence":"additional","affiliation":[{"name":"Institute for Chemical Technologies and Analytics Vienna University of Technology  Vienna Austria"}]},{"given":"Andras","family":"Gelencser","sequence":"additional","affiliation":[{"name":"Air Chemistry Group at the Hungarian Academy of Sciences University of Pannonia  Veszpr\u00e9m Hungary"}]},{"given":"Michel","family":"Legrand","sequence":"additional","affiliation":[{"name":"Laboratory for Glaciology and Geophysics of the Environment Centre National de la Recherche Scientifique  Saint Martin d'H\u00e8res France"}]},{"given":"Casimiro","family":"Pio","sequence":"additional","affiliation":[{"name":"Centre for Environmental and Marine Studies and Department of Environment University of Aveiro  Aveiro Portugal"}]}],"member":"13","published-online":{"date-parts":[[2007,8,14]]},"reference":[{"volume-title":"Air Composition and Chemistry","year":"1986","author":"Brimblecombe P.","key":"e_1_2_6_2_1"},{"volume-title":"Chemistry and Biochemistry of Herbage","year":"1973","author":"Butler G.
