The original version of this Article contained errors in the Introduction, Results and Discussion section, Figure 5 and 6, Acknowledgements section and in Supplementary Information 2 and 3.

In the Introduction,

“Chen et al.²⁴ showed that in Nagoya city, WISOM had higher contribution to the total light absorption of OA than that of WSOM and was dominant in the visible region.”

now reads:

“Chen et al.²³ showed that in Nagoya city, WISOM had higher contribution to the total light absorption of OA than that of WSOM and was dominant in the visible region.”

In the Results and Discussion section, under the subheading ‘Light absorption properties’,

“For WISOM, the MAE₃₆₅ was, on average, also lower than that at highly polluted urban sites in **’an and Bei**g (mean ± SD: 1.5 ± 0.5 m² g⁻¹ C and 1.5 ± 0.4 m² g⁻¹ C, respectively) and comparable with that in Nagoya (mean ± SD: 0.37 ± 0.13 m² g⁻¹)^23,24,30.”

now reads:

“For WISOM, the MAE₃₆₅ was, on average, also lower than that at highly polluted urban sites in **’an and Bei**g (mean ± SD: 1.5 ± 0.5 m² g⁻¹ C and 1.5 ± 0.4 m² g⁻¹ C, respectively) and comparable with that in Nagoya (mean ± SD: 0.37 ± 0.13 m² g⁻¹)^23,24.”

In the Results and Discussion section, under the subheading ‘Contribution of the OA fraction to total light absorption’,

“At 365 nm, the light absorption of the EOM was on average 2.7 Mm⁻¹, which was lower than that in **’an (65.4 Mm⁻¹) and Bei**g (42.1 Mm⁻¹)²⁴.”

now reads:

“At 365 nm, the light absorption of the EOM was on average 0.27 Mm⁻¹, which was lower than that in **’an (65.4 Mm⁻¹) and Bei**g (42.1 Mm⁻¹)²⁴.”

“The average light absorption of EOM at 365 nm was, on average, 2.1 and 5.0 Mm⁻¹ in summer and winter, respectively, which corresponded to 11% and 22% of the estimated total light absorption.”

now reads:

“The average light absorption of EOM at 365 nm was, on average, 0.21 and 0.50 Mm⁻¹ in summer and winter, respectively, which corresponded to 11% and 22% of the estimated total light absorption.”

In Figure 6, in the vertical axes “Light Absorption (10⁻⁵ m⁻¹)” was incorrectly given as “Light Absorption (10⁻⁶ m⁻¹)”. The original Figure 6 and accompanying legend appear below.

In the legend of Figure 5,

“Comparison of MAE₃₆₅ of HULIS from this study with the values at a background site³⁰, urban sites of East Asia^18,23,43,44 and urban sites of Europe⁴⁵. The bar indicates the standard deviation.”

To:
