Atmospheric and Hydrospheric Surface Loading Deformations

Vertical and horizontal deformations of the crust imposed by surface loading of geophysical fluids in atmosphere, oceans and the continental hydrosphere are provided with a spatial resolution of 0.5° and a temporal sampling of down to 3 hours. The elastic deformations are calculated via Green's Functions in two different reference frames (i.e., Center-of-Figure and Center-of-Mass) on the basis of Load Love Numbers given for the elastic Earth model ak135 (Kennett et al., 1995). The time-series start in January 1976 and are routinely updated every day at ~10:00 UTC with all 8 time-steps of the previous day. In addition, 3-hourly forecasts for up to 6 days into the future are also provided.
