dip of the horizon

The angular difference between the horizontal and the direction to the horizon.

Leaving aside displacements due to topography (mountains and valleys), the horizon can be displaced from the horizontal by the earth's curvature, by the elevation of the observer, and by the refraction of light in the atmosphere.
