BackForward Variable: Precipitation intensity at surface (liquid or solid)

Definition
Full name Precipitation intensity at surface (liquid or solid)
Definition Intensity of precipitation reaching the ground - Physical unit: [ mm/h ] (if solid, mm/h of liquid water after melting) - Accuracy unit: [ mm/h ]. Since accuracy changes with intensity, it is necessary to specify a reference intensity. Assumed rate: 5 mm/h.
Measuring Units mm/h Uncertainty Units mm/h
Horizontal Res Units km Vertical Res Units N/A
Stability Units mm/h (Stability /decade)

 

Comment: This variable merges "Precipitation rate (liquid) at the surface" and "Precipitation rate (solid) at the surface".
