Influences of the NAO on the North Atlantic CO2 Fluxes in Winter and Summer on the Interannual Scale

Highlights
• There is a large difference in the fCO2-NAO relationship between winter and summer in the subtropical region.

• On the interannual scale, the fCO2 variation is dominated by NAO-driven wind speed anomalies in winter, but by surface-ocean pCO2sea in summer.

• The pCO2sea variation is dominated by NAO-driven SSTs in the subtropical region and by other factors in the subpolar region.

Highlights
• Liquid water can affect the formation of O3 and SOA from 1,2,3-trimethylbenzene.

• The hygroscopic growth factors of SOA from 1,2,3-trimethylbenzene were measured.

• Hydrolysis of N2O5 is the major reason for the decrease of O3.

• The major contribution of SOA under high LWC conditions comes from aqueous reaction.

Collaborative publication: Effect of RH on SOA from cyclohexene

Influence of relative humidity on cyclohexene SOA formation from OH photooxidation
RH on SOA from cyclohexene.jpg

Highlights
• Combined effects of OH and RH on cyclohexene SOA formation were studied.

• The formation of oligomers at high RH was responsible for the increase of the SOA yield.

• High RH increases the OH uptake coefficient of SOA, and promotes SOA aging.

• Oligomers formation mechanism from cyclohexene photooxidation at high RH was proposed.
