BackForward Variable: Cloud to Ground lightning density

Definition
Full name Cloud to Ground lightning density
Definition Number of detected cloud-to-ground flashes in the corresponding time interval and the space unit. The space unit (grid box) should be equal to the horizontal resolution and the accumulation time to the observing cycle
Measuring Units Dimensionless Uncertainty Units Dimensionless
Horizontal Res Units km Vertical Res Units N/A
Stability Units %/decade (Stability /decade)
