Variable: Wave directional energy frequency spectrum

Definition
Full name Wave directional energy frequency spectrum
Definition 2D variable colloquially referred to as wave spectrum. Describes the wave energy travelling in each direction and frequency band (e.g., 24 distinct azimuth sectors each 15° wide, and 25 frequency bands)
Measuring Units m2 . Hz-1 . rad-1 Uncertainty Units m2 . Hz-1 . rad-1
Horizontal Res Units km Vertical Res Units
Stability Units m2 . Hz-1 . rad-1 (Stability /decade)
