Fig. 4: Secondary organic aerosol (SOA) changes, aerosol scattering forcing, cloud droplet number concentration changes and associated cloud forcing.
From: Chemistry-driven changes strongly influence climate forcing from vegetation emissions
Difference in (a) zonal mean SOA increase and (b) accumulation mode SOA column increase between CRI-Strat 2 (CS2Δ) and Strat-Trop (STΔ). Radiative forcing from the change in the aerosol direct radiative effect (IRFDRE) for (c) STΔ and (d) CS2Δ. Percentage change in vertically averaged cloud droplet number concentration (CDNC) concentration (e) STΔ and (f) CS2Δ and radiative forcing due to change in CDNC (ERFCDNC) for (g) ST∆ and (h) CS2∆ calculated using the offline approach of34 (Methods). Values in titles are global mean forcing (c, d) and CDNC change (e, f). Non-hatched regions in (c–h) show areas where the change is statistically significant (95% confidence).
