Description:
The Libya gravimetric geoid model extends from 20° N to 35° N in latitude and 9° E to 25° E in longitude with a grid resolution of 5' x 5'. It was computed by using Stokes' integral in the framework of a remove-restore procedure. The integral is evaluated in the frequency domain by the multi-band Fast Fourier Transform approximation with a proper zero padding. The used data were: 5' x 5' gridded values of Bouguer anomalies (onshore) and free-air anomalies (offshore) released for geoid computation by GETECH, a 5' x 5' global digital terrain model and the EGM96 global geopotential model.
