Local and remote temperature response of regional SO2 emissions
Lewinschal, Anna; Ekman, Annica M. L.; Hansson, Hans-Christen; Sand, Maria; Berntsen, Terje Koren; Langner, Joakim (Journal article; Peer reviewed, 2019)Short-lived anthropogenic climate forcers (SLCFs), such as sulfate aerosols, affect both climate and air quality. Despite being short-lived, these forcers do not affect temperatures only locally; regions far away from the ... -
Luftfart og klima - En oppdatert oversikt over status for forskning på klimaeffekter av utslipp fra fly
Lund, Marianne Tronstad; Aamaas, Borgar; Berntsen, Terje Koren; Fuglestvedt, Jan S. (2016:05, Research report, 2016)Denne rapporten gir en oppdatert oversikt over hvordan og i hvilken grad de ulike utslippene fra flytrafikk påvirker klima basert på den nyeste forskningen. For å forstå den totale klimaeffekten av luftfart er det viktig ... -
Metodikk for framstilling av klimaeffekt på kort og lang sikt
Aamaas, Borgar; Berntsen, Terje Koren (CICERO Report, Research report, 2021)CICERO Senter for klimaforskning har på oppdrag fra Miljødirektoratet utviklet og illustrert metodikk for framstilling av klimaeffekt på kort og lang sikt. Vi har vurdert klimaeffekt på to forskjellige måter, med vektfaktorer ... -

Mužić, Iris; Vestin, Patrik; Lindroth, Anders; Mölder, Meelis; Biermann, Tobias; Heliasz, Michal; Rinne, Janne; Berntsen, Terje Koren; Hodnebrog, Øivind; Sillmann, Jana; Yilmaz, Yeliz A. (Poster, 2021) -
NOx emissions from aircraft: Effects of lightning and convection on changes in tropospheric ozone
Berntsen, Terje Koren; Isaksen, Ivar S. A. (1998:05, Working paper, 1998)A global 3-dimensional chemical tracer model (CTM) has been used to study the impact on tropospheric ozone caused by NOx emissions from today’s fleet of subsonic aircraft (0.52 Tg(N)/yr), due to uncertainties in sources ... -
Radiative forcing of the direct aerosol effect from AeroCom Phase II simulations
Myhre, Gunnar; Samset, Bjørn Hallvard; Schulz, M.; Balkanski, Y.; Bauer, S.; Berntsen, Terje Koren; Bian, H.; Bellouin, N.; Chin, M; Diehl, T; Easter, R. C.; Feichter, J; Ghan, SJ; Hauglustaine, D; Iversen, Trond; Kinne, S; Kirkevåg, A; Lamarque, J. F.; Lin, G; Liu, X.; Lund, Marianne Tronstad; Luo, G; Ma, X; van Noije, T; Penner, JE; Rasch, P.

(Peer reviewed; Journal article, 2013)We report on the AeroCom Phase II direct aerosol effect (DAE) experiment where 16 detailed global aerosol models have been used to simulate the changes in the aerosol distribution over the industrial era. All 16 models ... -
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; 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 ... -
Responses in tropospheric O3, OH and CH4 to changed emissions of important trace gases
Fuglestvedt, Jan S.; Berntsen, Terje Koren; Isaksen, Ivar S. A. (1993:04, Research report, 1993)A two-dimensional (altitude vs. latitude) photochemical/transport model of the global troposphere is applied to study the effects of changed emissions of NOx, CH4, CO2 and NMHC on the levels of O3, OH and CH4. On a mass ... -
Sensitivity of black carbon concentrations and climate impact to aging and scavenging in OsloCTM2-M7
Lund, Marianne Tronstad; Berntsen, Terje Koren; Samset, Bjørn Hallvard (Peer reviewed; Journal article, 2017)Accurate representation of black carbon (BC) concentrations in climate models is a key prerequisite for understanding its net climate impact. BC aging and scavenging are treated very differently in current models. Here, ... -
