Nephele E3SMv3 PPE

Nephele global mean physical behaviors and parameter influence.

Nephele E3SMv3 PPE global mean physical behaviors. Linear regression (a) r2 value and (b) slope for global mean behaviors (y-axis) on perturbed parameters parameters (x-axis). Solid boxes in (b) indicate results that fall within the 95% confidence interval. Figure from Nugent et al. (2025).

Nephele global mean PI to PD change in Nd, LWP, and SW CRE (ERFaci).

Nephele E3SMv3 PPE preindustrial (PI) to present-day (PD) change in global mean quantities. PI to PD changes (∆=PD-PI) in cloud drop number concentration (Nd) and liquid water path (LWP) shaded by shortwave effective radiative forcing from aerosol-cloud interactions (ERFaci). Each dot represents an ensemble member. The default configuration of E3SMv3 is shown in the larger dot and star in the color bar. Figure from <a class=”reference external” href=”https://doi.org/10.22541/essoar.174907165.57104591/v1”>Nugent et al. (2025)</a>.

ARM observational constraints on ∆Nd.

ARM observational constraints on higher end of expert assessed ∆Nd. Observational constraints of ΔNd using the multi-linear regression (MLR) for Nd and surface CCN at supersaturation 0.1% as well as a simple regression using just Nd for each of the sites. Each bar represents the 90% confidence interval. Figure from Jones et al. (2025).
