NLOADF - A PROGRAM FOR COMPUTING OCEAN-TIDE LOADING

The loading of the Earth by the ocean tides produces several kinds of signals which can be measured by geodetic technique. In order to compu te these most accurately; a combination of global and local models of the ocean tides may be needed. The program NLOADF convolves the Green functions for loading with ocean tide models using a station-centered grid with fixed dimensions, making it easy to combine different ocean models without overlap in the convolution. The program computes all th e quantities of interest (gravity, displacement, tilt, and strain) and includes the case where measurements are made beneath the surface of the ocean.
