Three different environmental loading methods are used to estimate surface displacements
and correct non-linear variations in a set of GPS weekly height time series. Loading data are …

Ocean bottom pressure (OBP) changes are caused by a redistribution of the ocean's internal
mass that are driven by atmospheric circulation, a change in the mass entering or leaving …

We analyzed the impacts of data span on trend estimates using Earth's long-term polar
motion time series, 1846-present, and using methodologies including singular spectrum …

Seasonal deformation related to mass redistribution on the Earth's surface can be recorded
by continuous global navigation satellite system (GNSS) and simulated by surface loading …

We use temporal gravity variations from GRACE to investigate changes in a 34‐year time
series of Earth's oblateness (J2) observed by satellite laser ranging (SLR). We use 2002 …

The Earth's oblateness varies slightly due to a host of physical processes that involve large‐
scale meridional N‐S mass redistributions in the Earth. We analyze these minute …

The terrestrial reference frame is a cornerstone for modern geodesy and its applications for
a wide range of Earth sciences. The underlying assumption for establishing a terrestrial …

In the framework of satellite-only gravity field modeling, satellite laser ranging (SLR) data is
typically exploited to recover long-wavelength features. This contribution provides a detailed …

This study investigated the nonlinear changes in the vertical motion of 411 GNSS reference
stations situated in mainland China and assessed the influence of the environmental load …

We present a new approach to estimate time variations in J 2. Those variations are
represented as the sum of contributions from individual sources. This approach uses solely …
