Improvements on existing geopotential coefficients models for precise determination of 1° global geoid and mean gravity anomalies
Abstract The concept of an idealised earth having 1° averaged heights over its land surface is introduced as a means to improve upon the existing geopotential coefficient solutions without the use of additional observed data, in order to provide more precise knowledge of the earth’s gravity field in the form of 1° global geoid and 1° mean free-air gravity anomalies especially over the mountainous regions with the visible topography condensed into the actual geoid, first by referring them to the idealised earth and then by reducing the same to the actual earth on applying appropriate corrections for the differences between the two earths.
