Earth’s Centre of Mass Shifts Millimetres Annually Due to Water and Air Movements

A recent geodetic study uses satellite ranging, GPS, and orbital data to measure the annual millimetre-scale shift of Earth's centre of mass relative to its solid surface. This shift is caused by the redistribution of weight from monsoon rains, snowpack, ocean water, and shifting air masses. The findings provide precise insight into how natural processes affect Earth's mass distribution over the course of each year.
