Autor: R. Lapere, L. Marelle, P. Rampal, L. Brodeau, C. Melsheimer, G. Spreen, J. L. Thomas

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 12107-12132 (2024)

Elongated open-water areas in sea ice (leads) release sea spray particles to the atmosphere. However, there is limited knowledge on the amount, properties and drivers of sea spray emitted from leads, and no existing parameterization of this process i

Evaluating modelled tropospheric columns of CH4, CO, and O3 in the Arctic using ground-based Fourier transform infrared (FTIR) measurements

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 1079-1118 (2024)

This study evaluates tropospheric columns of methane, carbon monoxide, and ozone in the Arctic simulated by 11 models. The Arctic is warming at nearly 4 times the global average rate, and with changing emissions in and near the region, it is importan

Arctic tropospheric ozone: assessment of current knowledge and model performance

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 637-661 (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 recent research on observations

Comparison of model and ground observations finds snowpack and blowing snow aerosols both contribute to Arctic tropospheric reactive bromine

Autor: W. F. Swanson, C. D. Holmes, W. R. Simpson, K. Confer, L. Marelle, J. L. Thomas, L. Jaeglé, B. Alexander, S. Zhai, Q. Chen, X. Wang, T. Sherwen

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 14467-14488 (2022)

Reactive halogens play a prominent role in the atmospheric chemistry of the Arctic during springtime. Field measurements and modeling studies suggest that halogens are emitted into the atmosphere from snowpack and reactions on wind-blown snow-sourced

Model evaluation of short-lived climate forcers for the Arctic Monitoring and Assessment Programme: a multi-species, multi-model study

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 5775-5828 (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 sensitive, pristine region th
