Aerosol absorption in global models from AeroCom phase III
(Peer reviewed; Journal article, 2021)Aerosol-induced absorption of shortwave radiation can modify the climate through local atmospheric heating, which affects lapse rates, precipitation, and cloud formation. Presently, the total amount of aerosol absorption ... -
Arctic tropospheric ozone: assessment of current knowledge and model performance
(Peer reviewed; Journal article, 2023)As the third most important greenhouse gas (GHG) after carbon dioxide (CO2) and methane (CH4), tropospheric ozone (O3) is also an air pollutant causing damage to human health and ecosystems. This study brings together ... -
Black carbon aerosol reductions during COVID-19 confinement quantified by aircraft measurements over Europe
(Peer reviewed; Journal article, 2022)The abrupt reduction in human activities during the first lockdown of the COVID-19 pandemic created unprecedented atmospheric conditions. To quantify the changes in lower tropospheric air pollution, we conducted the BLUESKY ... -
CO2-equivalence metrics for surface albedo change based on the radiative forcing concept: a critical review
(Journal article, 2021)Management of Earth’s surface albedo is increasingly viewed as an important climate change mitigation strategy both on (Seneviratne et al., 2018) and off (Field et al., 2018; Kravitz et al., 2018) the land. Assessing the ... -
Competing effects of aerosol reductions and circulation changes for future improvements in Beijing haze
(Journal article; Peer reviewed, 2021)Despite local emission reductions, severe haze events remain a serious issue in Beijing. Previous studies have suggested that both greenhouse gas increases and aerosol decreases are likely to increase the frequency of ... -
The Emissions Model Intercomparison Project (Emissions-MIP): Quantifying model sensitivity to emission characteristics
(Peer reviewed; Journal article, 2023)Anthropogenic emissions of aerosols and precursor compounds are known to significantly affect the energy balance of the Earth–atmosphere system, alter the formation of clouds and precipitation, and have a substantial impact ... -
Implications of differences between recent anthropogenic aerosol emission inventories for diagnosed AOD and radiative forcing from 1990 to 2019
(Peer reviewed; Journal article, 2023)This study focuses on implications of differences between recent global emissions inventories for simulated trends in anthropogenic aerosol abundances and radiative forcing (RF) over the 1990–2019 period. We use the ECLIPSE ... -
Influence of weather situation on non-CO2 aviation climate effects: The REACT4C climate change functions
(Journal article; Peer reviewed, 2021)Emissions of aviation include CO2, H2O, NOx, sulfur oxides, and soot. Many studies have investigated the annual mean climate impact of aviation emissions. While CO2 has a long atmospheric residence time and is almost ... -
Mapping the dependence of black carbon radiative forcing on emission region and season
(Peer reviewed; Journal article, 2022)For short-lived climate forcers such as black carbon (BC), the atmospheric concentrations, radiative forcing (RF), and, ultimately, the subsequent effects on climate, depend on the location and timing of the emissions. ... -
Model evaluation of short-lived climate forcers for the Arctic Monitoring and Assessment Programme: a multi-species, multi-model study
(Journal article; Peer reviewed, 2022)While carbon dioxide is the main cause for global warming, modeling short-lived climate forcers (SLCFs) such as methane, ozone, and particles in the Arctic allows us to simulate near-term climate and health impacts for a ... -
Numerical simulation and evaluation of global ultrafine particle concentrations at the Earth's surface
(Peer reviewed; Journal article, 2023)A new global dataset of annually averaged ultrafine particle (UFP) concentrations at the Earth's surface for the years 2015–2017 has been developed through numerical simulations using the ECHAM/MESSy Atmospheric Chemistry ... -
Responses of Arctic black carbon and surface temperature to multi-region emission reductions: A Hemispheric Transport of Air Pollution Phase 2 (HTAP2) ensemble modeling study
(Journal article; Peer reviewed, 2021)Black carbon (BC) emissions play an important role in regional climate change in the Arctic. It is necessary to pay attention to the impact of long-range transport from regions outside the Arctic as BC emissions from local ... -
Satellite-based evaluation of AeroCom model bias in biomass burning regions
(Peer reviewed; Journal article, 2022)Global models are widely used to simulate biomass burning aerosol (BBA). Exhaustive evaluations on model representation of aerosol distributions and properties are fundamental to assess health and climate impacts of BBA. ... -
Technical note: Emulation of a large-eddy simulator for stratocumulus clouds in a general circulation model
(Peer reviewed; Journal article, 2024)Here we present for the first time a proof of concept for an emulation-based method that uses a large-eddy simulations (LESs) to present sub-grid cloud processes in a general circulation model (GCM). We focus on two key ...
