The original version of this Article contained errors in the Reference list.


The authors omitted the below References, which are now listed as References 46 and 48.

In addition, References 44 and 47 were provided in the Reference List but not cited in the body of the text.


As a result, in the Methods section, subheading ‘Collection and analysis of bulk surface sweater samples‘,


“Suzuki et al.17 described how phytoplankton pigments were extracted with a DMF-bead-beating technique and analyzed using ultra-high-performance liquid chromatography (UHPLC)42.”


now reads:


“Suzuki et al.17 described how phytoplankton pigments were extracted with a DMF-bead-beating technique and analyzed using ultra-high-performance liquid chromatography (UHPLC)44.”


Under the subheading ‘Stable carbon isotopic characterization of the aerosols‘,


“Also, the δ13C of total carbon (δ13CTC) (i.e., without water extraction) was measured with the EA–IRMS for the same aerosol filter samples.”


now reads:


“Also, the δ13C of total carbon (δ13CTC) (i.e., without water extraction) was measured with the EA–IRMS for the same aerosol filter samples46.”


Under the subheading ‘Offline measurement and determination of hygroscopicity κ‘,


“That particle size is in the range of particles that activate as CCN at supersaturations lower than 1.0%, which are typically found in the ambient atmosphere41.”


now reads:


“That particle size is in the range of particles that activate as CCN at supersaturations lower than 1.0%, which are typically found in the ambient atmosphere41,47.”


Under the same heading,


“Whereas the other stream was channeled into a continuous-flow thermal-gradient diffusion chamber (CCN-100, Droplet Measurement Technologies) to measure the number concentration of CCN (NCCN)47”.


now reads:


“Whereas the other stream was channeled into a continuous-flow thermal-gradient diffusion chamber (CCN-100, Droplet Measurement Technologies) to measure the number concentration of CCN (NCCN)48.”


And,


“Further details of the instrumental setup and the calculation of hygroscopicity κ are described by Müller et al.47.”


now reads:


“Further details of the instrumental setup and the calculation of hygroscopicity κ are described elsewhere48,50.”


As a result of the changes, References were renumbered accordingly.


Lastly, the Acknowledgements section was incomplete.
