BackForward Variable: Cloud liquid water (CLW) total column

Definition
Full name Cloud liquid water (CLW) total column
Definition 2D Field of atmospheric water in the liquid phase (precipitating or not), integrated over the total column.
Measuring Units g.m-2 Uncertainty Units g.m-2
Horizontal Res Units km Vertical Res Units
Stability Units g.m-2 (Stability /decade)

 

Comment: This variable is identical to the "Cloud Liquid Water Path" which is used in GCOS and given in measuring and uncertainty units of Kg m-2.
