Characteristics of Aerosol WSI With High‐Time‐Resolution Observation Over Arctic Ocean

Abstract

In the current study, the characteristics of aerosol water-soluble ions (WSI) were investigated via high-time-resolution observations as part of the nineth Chinese National Arctic Research Expedition (CHINARE) in 2018. WSI, including Cl − , SO 4

Importance of Atmospheric Transport on Methanesulfonic Acid (MSA) Concentrations in the Arctic Ocean During Summer Under Global Warming

“…Yu et al. (2020) found that the average MSA concentration in the HAO was 0.02 μg/m 3 with the CHINARE 2018 cruise. Sharma et al.…”

“…Sharma et al (2012) found that the average MSA concentration was 0.02 μg/m 3 at Barrow Station (Utqiaġvik, near the Chukchi Sea) during summer. Yu et al (2020) found that the average MSA concentration in the HAO was 0.02 μg/m 3 with the CHINARE 2018 cruise. Sharma et al (2012) found that the MSA concentration averaged 0.042 μg/m 3 at the Ny-Ålesund site (Svalbard Islands, near to the cruise route in NG) during summer, and it had an extremely high maximum MSA concentration of approximately 0.2 μg/m 3 .…”

“…Presently, ample observational data on MSA concentration in the Arctic Ocean are available, and the concentration is approximately 0.01–0.04 μg/m 3 (Moffett et al., 2020; Sharma et al., 2012; Yu et al., 2020). Many studies have been conducted on the inter‐annual and seasonal variations in MSA concentrations in the Arctic Ocean and their influencing factors.…”
