This PDF file includes:

  • Fig. S1. The AeroCom scenario B and PRE SO4 column density (black) across eight models (MPI-HAM excluded due to unavailability of SO4 column density) and difference in SO4 column density (μg/m2) between preindustrial and present day (red).
  • Fig. S2. The AeroCom scenario B and PRE SO4 surface concentration from LSCE, GISS, LOA, and UIO-GCM.
  • Fig. S3. The fractional change in SO4 surface concentration between the presentday and preindustrial period from AeroCom scenario B and PRE SO4 surface concentration from LSCE, GISS, LOA, and UIO-GCM.
  • Fig. S4. Tenfold cross-validation performed using only POP/BEC-modeled chlorophyll-consistent quantities.
  • Fig. S5. Contribution of the labile “lipid-like” group and total contribution of the semi-labile “polysaccharide-like” and “protein-like” groups to the total Nd from the regression model.
  • Fig. S6. The 10-fold cross-validation repeated using wind speed from the Multi-Platform Ocean Surface Wind Velocity L3.5, SST from the NOAA OI data product, SS aerosol concentration from AeroCom, and DMS (50).
  • Fig. S7. Scatter plot of lipid-like OMF in SSA as calculated by B14 as a function of POP chlorophyll.
  • Fig. S8. Tenfold cross-validation performed using only SeaWiFS consistent Chla.
  • Fig. S9. Tenfold cross-validation repeated using wind and SS concentration in addition to OMB14 and SO4 concentration.
  • Fig. S10. As in fig. S1, but averaged over 5° latitude × 5° longitude bins.
  • Table S1. Correlation coefficients in space and time using labile and semi-labile fields from B14.
