Elevated stratopause events in the current and a future climate: A chemistry-climate model study
(Peer reviewed; Journal article, 2021)The characteristics and driving mechanisms of Elevated Stratopause Events (ESEs) are examined in simulations of the ECHAM/MESSy Atmospheric Chemistry (EMAC) chemistry-climate model under present and projected climate ... -
Impact of solar irradiance and geomagnetic activity on polar NOx, ozone and temperature in WACCM simulations
(Peer reviewed; Journal article, 2020)The response of the atmosphere to solar irradiance and geomagnetic activity is analyzed in experiments with the Whole Atmosphere Community Climate Model (WACCM) under idealized forcings. Four experiments are carried out ... -
Impact of the major SSWs of February 2018 and January 2019 on the middle atmospheric nitric oxide abundance
(Peer reviewed; Journal article, 2021)The Arctic middle atmosphere was affected by major sudden stratospheric warmings (SSW) in February 2018 and January 2019, respectively. In this article, we report for the first time the impact of these two events on the ... -
Modelling the descent of nitric oxide during the elevated stratopause event of January 2013
(Journal article; Peer reviewed, 2017) -
Nighttime mesospheric ozone enhancements during the 2002 southern hemispheric major stratospheric warming
(Journal article; Peer reviewed, 2018) -
Semidiurnal nonmigrating tides in low-latitude lower thermospheric NO: A climatology based on 20 years of Odin/SMR measurements
(Peer reviewed; Journal article, 2023)The Sub-Millimetre Radiometer (SMR) on board the Odin satellite provides almost 20 years of nitric oxide (NO) measurements in the mesosphere and lower thermosphere (MLT) at equatorial crossing local solar times (LSTs) of ... -
WACCM simulations: Decadal winter-to-spring climate impact on middle atmosphere and troposphere from medium energy electron precipitation
(Peer reviewed; Journal article, 2020)Energetic particle precipitation is one of the main processes by which the sun influences atmospheric composition and structure. The polar middle atmosphere is chemically disturbed by the precipitation-induced production ...
