  1. 1. Primary and secondary organics in biogenic atmospheric aerosol : The chiral study of 2-methyltetrols from method development to application

    Författare :Nélida Jocelyn Donají Karlsson; Kevin Noone; Sandro Fuzzi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric organic aerosols; 2-methyltetrols; isoprene; chiral GC-MS; enantiomeric composition; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Distinguishing between the primary and secondary origin of the organic components in atmospheric aerosols is one of the key parameters in assessing the relevance and role of different chemical species in the overall chemistry of the atmosphere. Currently available methods used in field measurements are not able to fully discriminate between the primary or secondary origin of compounds detected in atmospheric aerosols. LÄS MER

  3. 2. Bioaerosols and their importance for low-level Arctic clouds

    Författare :Gabriel Pereira Freitas; Paul Zieger; Radovan Krejci; Kevin J. Noone; Claudia Mohr; Martin Gallagher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bioaerosols; Aerosols; Clouds; Arctic; Cloud Condensation Nuclei; Ice Nucleating Particles; Sea Spray Aerosol; Environmental Sciences; miljövetenskap;

    Sammanfattning : Bioaerosols are microorganisms or functional parts of them or other biological matter suspended in air. Examples are bacteria, viruses, pollen, spores, or smaller plant debris. In the atmosphere, bioaerosols can play various functional roles, such as facilitating the spread of genetic material. LÄS MER

  4. 3. Regime Shifts in the Anthropocene

    Författare :Juan Carlos Rocha; Garry Peterson; Reinette Biggs; Örjan Bodin; Kevin Noone; Sarah Cornell; Ingo Fretzer; Steven Lade; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; regime shifts; critical transitions; network analysis; dynamic tipping points; Sustainability Science; vetenskap om hållbar utveckling; Systems Ecology; systemekologi;

    Sammanfattning : Regime shifts are large, abrupt and often hard to reverse changes in the function and structure of socal-ecological systems. These regime shifts have been documented in a broad range of systems and scales both in marine, terrestrial and polar ecosystems. LÄS MER
