Detrended 60-day estimates of the geocenter motion from LAGEOS1+LAGEOS2 from 1998 to present (updated every 2 months).

The geocenter vector is consistent with IERS conventions, being the vector from the origin of the TRF to the instantaneous mass center of the Earth.

These results are updated from Ries, 2016 (https://cddis.nasa.gov/lw20/docs/2016/papers/14-Ries_paper.pdf)

The geocenter motion is the full signal; no Atmosphere-Ocean Dealiasing (AOD-1B) component has been removed.

This research was sponsored by the NASA/JPL MEaSUREs-2018 program. Computational resources provided by the University of Texas Advanced Computating Center.
