Variable: Cloud drop effective radius

Definition
Full name Cloud drop effective radius
Definition Size distribution of liquid water drops, assimilated to spheres of the same volume. Considered as both a 3D field throughout the troposphere and a 2D field at the top of cloud surface.
Measuring Units μm Uncertainty Units μm
Horizontal Res Units km Vertical Res Units
Stability Units μm (Stability /decade)
