Three-dimensional statistical gravity disturbance model
Janardan G. Negi, Vijay Prasad Dimri · Geophysical Journal International · 1977
The study proposes a three-dimensional gravity disturbance model to consider hitherto the unaccounted effect of the altitude. For this, secondorder statistics for the gravity disturbance vector and its components have been derived using Poisson's integral. The modified Wiener-Khintchine theorem has been used in the analysis and some of the existing models, proposed earlier, have been reassessed which brings out noticeable departure in their interpretation. The application of the Jordan criterion shows that under the restriction of localized anomaly, Vyskocil's (cosine exponential anomaly) model may be considered realistic.
