  • A continued role of short-lived climate forcers under the Shared Socioeconomic Pathways 
    Lund, Marianne Tronstad; Aamaas, Borgar; Stjern, Camilla Weum; Klimont, Zbigniew; Berntsen, Terje Koren; Samset, Bjørn Hallvard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Mitigation of non-CO2 emissions plays a key role in meeting the Paris Agreement ambitions and sustainable development goals. Implementation of respective policies addressing these targets mainly occur at sectoral and ...
  • Climate effects of non-compliant Volkswagen diesel cars 
    Tanaka, Katsumasa; Lund, Marianne Tronstad; Aamaas, Borgar; Berntsen, Terje Koren (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    On-road operations of Volkswagen light-duty diesel vehicles equipped with defeat devices cause emissions of NOx up to 40 times above emission standards. Higher on-road NOx emissions are a widespread problem not limited to ...
  • Developing, evaluating, and applying emission metrics for the assessment of the climate impact of transportation 
    Aamaas, Borgar (Doctoral thesis / Doktoravhandling, 2016)
  • Elemental carbon in Svalbard snow from local sources and its impact on surface albedo 
    Aamaas, Borgar (Master thesis / Masteroppgave, 2009)
    Svalbard, ei øygruppe i Arktis, vert påverka både av langtransportert og lokal forureining. I denne oppgåva har konsentrasjonar av elementært karbon (EC) i snøen og effekten det har på albedo blitt undersøkt. Eit overslag ...
  • Emission metrics for quantifying regional climate impacts of aviation 
    Lund, Marianne Tronstad; Aamaas, Borgar; Berntsen, Terje Koren; Bock, Lisa; Burkhardt, Ulrike; Fuglestvedt, Jan S.; Shine, Keith P (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    This study examines the impacts of emissions from aviation in six source regions on global and regional temperatures. We consider the NOx-induced impacts on ozone and methane, aerosols and contrail-cirrus formation and ...
  • Regional temperature change potentials for short-lived climate forcers based on radiative forcing from multiple models 
    Aamaas, Borgar; Berntsen, Terje Koren; Fuglestvedt, Jan S.; Shine, Keith P; Collins, William J (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    We calculate the absolute regional temperature change potential (ARTP) of various short-lived climate forcers (SLCFs) based on detailed radiative forcing (RF) calculations from four different models. The temperature response ...
  • The regional temperature implications of strong air quality measures 
    Aamaas, Borgar; Berntsen, Terje Koren; Samset, Bjørn Hallvard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Abstract. Anthropogenic emissions of short-lived climate forcers (SLCFs) affect both air quality and climate. How much regional temperatures are affected by ambitious SLCF emission mitigation policies is, however, still ...
