Pagination or Media Count:
The publication contains the explanations of the methods used in computing the 1 degree x 1 degree mean free-air gravity anomaly values and their accuracies. The information contained in this report is in two parts. Part I identifies each computational method, gives a written definition, and furnishes the equations with a sample computation. When and how the method should be used and any strengths and shortcomings of the method are addressed. Part II identifies the method used to arrive at an accuracy value for each computational method, gives a written definition with associated equations, and provides a sample computation. Shortcomings of the methods are stated.
