-- See Also the narrower term Atmospheric physics Here are entered works on the physical rather than chemical or dynamical aspects of the atmosphere of the earth and other planets.
-- See Also the narrower term Gravity Here are entered works relating to measurement of the resultant effect of the gravitational attraction and centrifugal repulsion between any body and a planet or other celestial body, including works on earth's gravity.
