Loading displacements are computed by invoking the so-called inverted barometer hypothesis. It is considered that ocean reacts to the atmospheric pressure variations by perfectly counter-balancing them, so the total pressure variations at the ocean bottom remains constant.
Harmonic variations with periods around 1 days and shorter, the so-called atmospheric tides, were removed from the surface pressure. Therefore, the time series do not contain harmonic variations.
Time series of displacements are computed from 2 models developed by Global Modeling and Assimilation Office at NASA Goddard Space Flight Center:
Displacements in netCDF format to download. File size: 3.5–5.5 Mb per epoch, 6.1Gb/year (bzip2 compressed).
Auxiliary 3D displacements of the center mass of the total Earth with respect to the center mass of the solid Earth without atmosphere caused by atmospheric pressure loading. The sum of this displacement and the displacement wrt of the total mass, is the displacement with respect to the center of solid Earth, i.e. center of figure.
