SLR measures the Long-Term Dynamics of the Solid Earth, Oceans, and Ice Fields

Angular Momentum Exchange

SLR determinations of the Earth’s rotation and orientation reveal changes in the distribution of mass and exchange of angular momentum in the atmosphere-hydrosphere-cryosphere-solid Earth system.

Geocenter and station height variations

SLR determination of the changes in the geocentric height of stations coupled with determination of the motion of the station network with respect to the geocenter at the few mm level provides an unambiguous reference for studies of sea level variations and post-glacial rebound.

X-Motion Y-Motion

SLR provides a precise determination of the Earth’s crustal response to ocean and atmospheric loading.
