What Is Elevation Angle?
How far above the horizon the radar dish is pointed. Radars scan at several angles to build a 3D picture of storms. In technical terms: The angle of the radar beam axis above horizontal; WSR-88D volume coverage patterns sample from 0.5 degrees up to 19.5 degrees, and beam height at a given range increases with elevation angle and Earth curvature.
Also called: Tilt, Elevation Scan
Elevation Angle In Plain English
How far above the horizon the radar dish is pointed. Radars scan at several angles to build a 3D picture of storms.
The Technical Definition
The angle of the radar beam axis above horizontal; WSR-88D volume coverage patterns sample from 0.5 degrees up to 19.5 degrees, and beam height at a given range increases with elevation angle and Earth curvature.
