Earth oblateness
WebWhat causes the Earth's Oblateness? This is the result of the hydrostatic balance between the dominant gravitational force, which wants to pull the Earth into a spherically symmetric configuration, and the centrifugal force due to Earth's rotation, which wants to expel mass away from the rotating axis but in the end only manages to modify the Earth into ... WebJun 15, 2007 · Nevertheless there are geographic regions where the effect of the neglect of the Earth's oblateness can lead to small changes of the estimated parameters. Another …

Web1 Introduction. J 2, also known as the Earth's dynamic oblateness, is a fundamental parameter affecting the Earth's rotational behavior.Its time variations, ΔJ 2 (hereafter denoted as J 2 for simplicity), are driven by latitudinal large-scale mass redistributions in the Earth system, which are intimately associated with ongoing climate change (e.g., Cox & … Webthe Earth M a e is the semima jor axis of the Earths reference ellipsoid r are the satellite distance latitude and longitude resp ectiv ely in a b o dyxed co ordinate system C m S ... ts the oblateness of the Earth these co e cien ts corresp ond to the elliptici t y ab out the equator Also eviden t is that the magnitude of the co e cien ts ...
