Geophysical fluids data
Global geophysical fluids data provide information related to Earth rotation variation, gravity field variation and geocenter motion that are caused by mass transports in the global geophysical fluids (atmosphere, oceans, hydrology, tides, mantle, core).
All products are also available for download at the IERS https data download pages.
