Extended Data Fig. 4: Spatially-resolved radiative effect contribution for individual aerosols.
From: Natural short-lived halogens exert an indirect cooling effect on climate

The individual contribution arising from sulfate (a,b,c,d; top row), SOA (e,f,g,h; middle row) and ammonium nitrate (i,j,k,l; bottom row) for the AANE+ANT configuration are shown for pre-industrial (1st column; only NAT), present-day (2nd column), RCP 6.0 (3rd column) and RCP 8.5 (4th column) scenarios. The total contribution for all aerosols together is shown in the bottom row of Fig. 2 and Extended Data Fig. 2. The aerosol RE present a pronounced spatial variability (most notorious for ammonium nitrate, which has a predominant anthropogenic origin), with maximum impacts during present-day over industrialized regions such as Europe, North America and East Asia. The halogen-driven RE of sulfate aerosols during present-day (panel b) changes from positive to negative over China, in agreement with ref. 43. All maps and elements were created by our research group using Matplotlib Basemap for Phyton.
