The Prediction of Gravity in the United States Utilizing Geologic and Geophysics Parameters

摘要

Correlations developed between gravity anomalies and geologic and geophysical parameters were utilized for the prediction of gravity within the continental United States. The 2 degree x 2 degree mean free air anomalies predicted using the geologic-geophysical correlations had a mean error without regard to sign of 7 mgals and a r.m.s. error of 8.8 mgals. The predicted anomalies for 1 degree x 1 degree squares had a mean error without regard to sign of 10 mgals and a r.m.s. error of 12.9 mgals. (Author)
