Fig. 3: Impacts on ecosystems through diffuse radiation and deposition changes of different SAI materials.

From: Injecting solid particles into the stratosphere could mitigate global warming but currently entails great uncertainties

Fig. 3

Left column: changes in diffuse radiation (ultraviolet and visible, 250 nm–680 nm) normalized to ToA total sky RF for SO2 (a) and calcite (c) injection scenarios. Right column: the anomaly of the total sulfur-equivalent H2SO4 deposition flux of the SO2 injection scenario compared to the reference scenario (b) as well as the total deposition fluxes (sum of wet and dry deposition) of calcite particles at the surface (d). Dotted areas: statistically significant data in the 95% confidence interval (Student’s test), except for the deposition of calcite particles, for which no significance can be calculated. The scenarios with AM − H2SO4 and alumina injections (not shown) lead to similar deposition and scattered radiation patterns as SO2 and calcite, respectively.
