Atmospheric Loading and Mass Variation Effects on the SLR-Defined Geocenter

The geocenter time series can conveniently be inferred by evaluating satellite orbit perturbations in a dynamical model. We base our approach on nearly 30 years of Satellite Laser Ranging (SLR) observations to the LAGEOS satellites and recent model standards. We model station deformations by atmosph...

Zusammenfassung:The geocenter time series can conveniently be inferred by evaluating satellite orbit perturbations in a dynamical model. We base our approach on nearly 30 years of Satellite Laser Ranging (SLR) observations to the LAGEOS satellites and recent model standards. We model station deformations by atmospheric pressure loading and we model orbit perturbations by mass variations in the atmosphere. Both effects on the geocenter realization are analyzed.
