A triaxial reference ellipsoid for the Earth
We present a new, physically motivated triaxial reference ellipsoid for the Earth. It is an equipotential surface in the gravity field and closely...

Estimation of Earth Rotation Parameter UT1 from Lunar Laser Ranging Observations
Since 1969 Lunar Laser Ranging (LLR) data have been collected by different observatories and analysed by various analysis groups. LLR is providing...

Analysis of Differential Rotation of Anti‑Hale Active Regions
AbstractNumerous observations show that the rotation rates of active regions (ARs) across the solar disk are higher than those of the local plasma at...

Rotation of a Long-Lived Coronal Hole in Solar Cycle 24
AbstractThis paper discusses the results of a statistical study of the rotation characteristics of a long-lived giant coronal hole. The study is...

Gravity Field and Figure of the Earth
The shape of the Earth has always been a question of importance to humanity, with philosophical and religious aspects as well as practical ones,...
-
The Earth in the Solar System
We start with a discussion of the two milestones of Nature—the law of universal gravitation and Kepler’s laws, and the latter is the sequence of the...

Super-rotation independent of horizontal diffusion reproduced in a Venus GCM
Horizontal diffusion and resolution are important factors to generate and maintain the super-rotation in the general circulation model (GCM) because...

Performance evaluation of real-time orbit determination for LUTAN-01B satellite using broadcast earth orientation parameters and multi-GNSS combination
Real-time orbit determination (RTOD) for spacecraft using the space-borne GNSS technique needs earth orientation parameters (EOPs) for the required...

HOW SPECIAL IS THE EARTH?
Earth is the only planet in the solar system where complex life has evolved and persisted over billions of years. Of the more than 4,000 exoplanets...

Multidecadal variation of the Earth’s inner-core rotation
Differential rotation of Earth’s inner core relative to the mantle is thought to occur under the effects of the geodynamo on core dynamics and...

1 Entropy Production by Earth System Processes
Degradation of energy to lower temperatures and the associated production of entropy is a general direction for Earth system processes, ranging from...

PIONEERS: a 6DoF motion sensor to measure rotation and tides in the Solar System
Observation of rotation variations and tides provides constraints on the interior properties of celestial bodies. Both can be precisely measured with...

Paleomagnetic constraints on Paleogene-Neogene rotation and paleo-stress in the northern Qaidam Basin
Knowing the rotation and paleo-stress history in Qaidam Basin is a fundamental parameter to quantify the mechanism of intracontinental deformation in...

Assessment of length-of-day and universal time predictions based on the results of the Second Earth Orientation Parameters Prediction Comparison Campaign
Predicting Earth Orientation Parameters (EOP) is crucial for precise positioning and navigation both on the Earth’s surface and in space. In recent...

Microtremor-based analysis of the dynamic response characteristics of a site containing grouped earth fissures
In this study, the Beibu earth fissure site in the northeastern part of Weihe Basin, which contains four nearly parallel earth fissures, was studied....
