Time- and domain-average LWP (g m^{−2}), IWP (g m^{−2}), and time-average areal fraction of liquid water, F_{l} (no units), for the various sensitivity simulations. Values of F_{l} are calculated by assuming each grid cell has an instantaneous liquid fraction of 1 if the LWP exceeds 1 g m^{−2}, and 0 otherwise. M05 F_{s} indicates the sensitivity test with zero surface turbulent flux of water vapor, N_{I}N/10 indicates sensitivity tests with ice nuclei number concentration reduced by a factor of 10, N_{0}/10 indicates sensitivity tests with the snow size distribution intercept parameter reduced by a factor of 10, both/10 indicates sensitivity tests with both N_{0} and N_{I}N reduced by a factor of 10, and thresh indicates the sensitivity test allowing ice nucleation at temperatures >253 K only when liquid water is present.
