The impact of ice water path thresholds on the RFaci estimate, the forcing from $\mathcal{L}$ and f_l adjustments and the $\mathcal{L}$ and f_l enhancements of the RFaci. The row in bold represents the threshold value used throughout the rest of this work. The bottom rows show the liquid forcing estimates from a simulation with no parameterised cloud adjustment and determined from the standard simulation using the PRP method (Mülmenstädt et al., 2019). Values are in watts per square metre (Wm⁻²) unless otherwise specified.
