EGM_TIM_RL05: An independent geoid with centimeter accuracy purely based on the GOCE mission (2014, methodology): “These differences are supposed to be systematic errors in EGM2008 mainly in such regions where no, or low-quality, terrestrial data entered the computation of EGM2008 [Pavlis et al., 2012; Pail et al., 2011a; Bruinsma et al., 2013].”
The new ESA satellite‐only gravity field model via the direct approach (2013, background): “The spectrum of Earth Gravitational Model 2008 (EGM2008) [Pavlis et al., 2012] is given as reference.”
Gravity and Topography of the Terrestrial Planets (2015, methodology): “The largest gravitational anomalies are seen to be correlated with topography (such as trenches and seamounts), and the geoid height is found to vary by about 200 m. 10.05.3.1.3 Spectral analysis Spectral and cross-spectral properties of the shape model Earth2012 RET and the EGM2008 potential are pl”
ESA's satellite‐only gravity field model via the direct approach based on all GOCE data (2014, methodology): “Figure 1 shows the RMS values per degree of signal and error of DIR-R5, DIR-R4, the ﬁ fth release of ESA ’ s timewise model TIM-R5, and the reference model Earth Gravitational Model 2008 (EGM2008) [ Pavlis et al ., 2012].”
Toward 1-mGal accuracy in global marine gravity from CryoSat-2, Envisat, and Jason-1 (2013, background): “Along-track slopes from the 20-Hzretracked profiles are low-pass filtered at 14-km wavelength (0.5 gain) and a lower-resolution sea-surface height model [EGM2008, Pavlis et al., 2012] is removed from each profile.”
Gravity anomalies, crustal structure, and seismicity at subduction zones: 1. Seafloor roughness and subducting relief (2015, methodology): “Free-air gravity anomalies offshore are calculated from radar altimeter measurements of ocean-surface heights and are merged with subaerial gravity anomalies from the EGM2008 global gravity model [Sandwell and Smith, 2009; Pavlis et al., 2012].”
GECO: a global gravity model by locally combining GOCE data and EGM2008 (2016, neutral): “At the moment the most used ones are EGM2008 (Pavlis et al., 2012) and the EIGEN models (Förste et al.”
Gravity field recovery from geodetic altimeter missions (2019, methodology): “Residual alongtrack slopes (w.r.t. EGM2008; Pavlis et al., 2012) and uncertainties based on significant wave height were combined using a least squares biharmonic gridding approach (Wessel and Bercovici, 1998; Sandwell and Smith, 2009) to form grids of north and east deflection of the vertical.”
Towards a vertical datum standardisation under the umbrella of Global Geodetic Observing System (2012, methodology): “Nevertheless, numerical evaluations show that its accuracy in regions with dense terrestrial gravity coverage is about 10 cm while in poor covered areas it is 50 cmonly (Pavlis et al. 2012).”
New ultrahigh‐resolution picture of Earth's gravity field (2013, neutral): “[ 4 ] Our ultrahigh resolution picture of Earth ’ s gravity ﬁ eld is a combined solution based on the three key constituents GOCE/GRACE satellite gravity (providing the spatial scales of ~10,000 down to ~100 km), EGM2008 (~100 to ~10 km), and topographic gravity, i.e., the gravitational effect impli”
Deceleration in the Earth's oblateness (2013, methodology): “The ITRF2005 reference frame for tracking stations (specifically, SLRF2005/LPOD2005 [Ries, 2008]), the ocean pole tide [Desai, 2002], the FES2004 ocean (diurnal and semidiurnal) tides [Lyard et al., 2006], and the EGM2008 gravity model [Pavlis et al., 2012] were used in this analysis.”
