Abstract We statistically investigate fluctuation amplitudes (normalized to the background values) of dayside low‐/mid‐latitude upper‐thermospheric mass density as observed by Gravity Recovery and Climate Experiment (GRACE) GRACE‐Follow‐On (GRACE‐FO) spacecraft at ∼500 km altitude between 2002 2022. There are three new findings in our results. First, climatology closely replicates previous stud...

[1] Sea level in the Mediterranean Sea over the period 1993–2011 is studied on the basis of altimetry, temperature, and salinity data and gravity measurements from Gravity Recovery and Climate Experiment (GRACE) (2002–2010). An observed increase in sea level corresponds to a linear sea level trend of 3.0 0.5mm/yr dominated by the increase in the oceanic mass in the basin. The increase in sea le...

To better understand the impact of climate forcing on Greenland ice sheet (GrIS), we study GrIS mass variations interannual timescale as observed by satellite mission Gravity Recovery and Climate Experiment (GRACE). By employing method empirical orthogonal function) analysis, find: (a) That are significantly correlated with Pacific Decadal Oscillation, suggesting a connection to changes Iceland...

[1] One of the major problems one has to deal with when working with Gravity Recovery and Climate Experiment (GRACE) data is the increasing error spectrum at higher degrees in the provided Stokes coefficients, appearing as unphysical North-South striping patterns in the maps of equivalent water height (EWH). This phenomenon is commonly suppressed by application of a Gaussian smoothing filter, w...

The satellite mission GRACE (Gravity Recovery and Climate Experiment) provides monthly solutions of the global gravity field of the Earth. Temporal variations in gravity reflect mass redistributions over the Earth. Those mass movements are caused by physical phenomena such as ice sheet dynamics, accumulation of hydrological masses over land, the dynamics in the solid Earth and the dynamics in t...

[1] Antarctic volume changes during the past 21 thousand years are smaller than previously thought, and here we construct an ice sheet history that drives a forward model prediction of the glacial isostatic adjustment (GIA) gravity signal. The new model, in turn, should give predictions that are constrained with recent uplift data. The impact of the GIA signal on a Gravity Recovery and Climate ...

Abstract Land water storage plays a key role for the Earth’s climate, natural ecosystems, and human activities. Since launch of first Gravity Recovery Climate Experiment (GRACE) mission in 2002, spaceborne observations changes terrestrial (TWS) have provided unique, global perspective on human-induced freshwater resources. Even though they become much used within broader Earth system science co...

Monitoring the variations in terrestrial water storage (TWS) is crucial for understanding regional hydrological processes, which helps to allocate and manage basin-scale resources efficiently. In this study, impacts of climate change, glacier mass loss, human activities on TWS Qaidam Basin over period 2002−2020 were investigated by using Gravity Recovery Climate Experiment (GRACE) GRACE Follow-...
