Characterizing the hygroscopicity of growing particles in the Canadian Arctic summer

Autor: R. Y.-W. Chang, J. P. D. Abbatt, M. C. Boyer, J. P. Chaubey, D. B. Collins

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 8059-8071 (2022)

The impact of aerosols on clouds is a well-studied, although still poorly constrained, part of the atmospheric system. New particle formation (NPF) is thought to contribute 40 %–80 % of the global cloud droplet number concentration, although it is

Summertime Arctic aerosol size distributions are strongly controlled by natural regional emissions. Within this context, we use a chemical transport model with size-resolved aerosol microphysics (GEOS-Chem-TOMAS) to interpret measurements of aerosol

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Pp 13119-13138 (2017)

The source strength and capability of aerosol particles in the Arctic to act as cloud condensation nuclei have important implications for understanding the indirect aerosol–cloud effect within the polar climate system. It has been shown in sever

Publikováno v: Atmospheric Measurement Techniques, Vol 9, Iss 9, Pp 4257-4267 (2016)

In order to understand the processes governing the production of marine aerosols, repeatable, controlled methods for their generation are required. A new system, the miniature Marine Aerosol Reference Tank (miniMART), has been designed after the succ
