Industry:Earth science
The angle, expressed in degrees and measured westwards, from the plane of the hour circle passing through the vernal equinox to the plane of the hour circle passing through a point on the celestial sphere. It may also be defined as the angular distance on the celestial sphere, expressed in degrees and measured westward along the celestial equator, from the vernal equinox to the hour circle passing through the celestial body being observed. It is equal to 360<sup>o</sup> minus the right ascension in degrees.

A lease that attributes the use of public lands outside of grazing districts (Taylor Grazing Act) for the grazing of livestock for a specific period of time.
Industry:Earth science
The angle, measured westwards from the celestial meridian at Greenwich, from the plane of that celestial meridian to the plane of the hour circle passing through the celestial body observed. Greenwich hour angle is usually abbreviated to G.H.A. Or GHA. It may also be defined as the arc of the celestial equator, or the angle at the celestial pole, between the upper branch of the celestial meridian at Greenwich and the hour circle or a point on the celestial sphere, measured westward from the celestial meridian at Greenwich through 24 hours or 360<sup>o</sup>. It is the local hour angle at the Greenwich meridian.

Industry:Earth science
A graph of the discharge, speed, available power, or other property of a stream or conduit with respect to time. The most common type of hydrograph, the observed hydrograph, represents the readings on stream gages, plotted at the time of observation. Other types of hydrograph which are derived from the observations include the distribution graph and the unit hydrograph.
