Aggregation Errors of Cell-Averaged Geoid Height.

Abstract

The earth's surface is divided into approximately equal cells bounded by lines of constant longitude and latitude. The geoid height is averaged over each of these cells. The mean degree variance of the error thus committed in the geoid height is calculated. Mean degree variances higher than of the 45th degree are found to be in error by over 100% for 5 deg X 5 deg cells. The error committed by calculating the cell-averaged geoid height from discrete altimetry ground track is also estimated. It is found to be less than 10 cm for more than 3 tracks for 5 deg X 5 deg square sizes. (Author)
