Prescribed daily Holuhraun emissions used in the CESM2(CAM6) simulations47 (a), and timeseries showing monthly mean anomalies from the nudged (purple) and free-running (blue) CESM2(CAM6) simulations for the area north of \(60\,\,^{\circ }\)N and between \(30\,\,^{\circ }\)W and \(30\,\,^{\circ }\)E, excluding landmasses; (b) \(\hbox {SO}_4\) aerosol column burden, (c) vertically integrated cloud droplet number concentration, (d) vertically averaged cloud droplet effective radius, (e) cloud liquid water path, (f) downward shortwave radiative flux density at the surface, (g) downward longwave radiative flux density at the surface, and (h) surface air temperature. The blue shades indicate the 95% confidence intervals around the free-running ensemble means, open circles insignificant free-running anomalies, and filled circles significant ones. The red lines in (b)–(h) indicate the duration of the eruption. Note that (a) shows daily values but (b)–(h) monthly mean values. In (a), the ticks on the horizontal axis indicate the first day of each month.
