Accuracy of scaled GRACE terrestrial water storage estimates (2012, methodology): “…from signal degradation due to measurement errors and noise, which are manifested as both random errors that increase as a function of spherical harmonic spectral degree [Wahr et al., 2006], and systematic errors that are correlated within a particular spectral order [Swenson and Wahr, 2006].”
Quantifying renewable groundwater stress with GRACE (2015, methodology): “Gravity anomalies for this time period (January 2003 to December 2013) underwent processing to obtain an estimate of the average terrestrial water storage anomalies for each of the 37 study aquifers [Swenson and Wahr, 2002; Wahr et al., 2006; Swenson and Wahr, 2006].”

Improved Earth Oblateness Rate Reveals Increased Ice Sheet Losses and Mass‐Driven Sea Level Rise (2019, methodology): “With its launch in March 2002, GRACE initiated a new era for monitoring global water mass fluxes, providing monthly measurements of TVG to a spatial resolution of 300–500 km (Luthcke et al., 2013; Wahr et al., 2006).”
Interannual variations of the mass balance of the Antarctica and Greenland ice sheets from GRACE (2006, unknown): “Recently, Wahr et al. (2006) provided an error assessment of GRACE mass estimates.”
Increasing rates of ice mass loss from the Greenland and Antarctic ice sheets revealed by GRACE (2009, methodology): “We calculate errors in the GRACE data by convolving the averaging functions with uncertainty estimates for the GRACE Stokes coefficients as described by Wahr et al. [2006] .”
Replacing GRACE/GRACE‐FO C30 With Satellite Laser Ranging: Impacts on Antarctic Ice Sheet Mass Change (2020, background): “The Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GRACE-FO) missions have revolutionized our ability to monitor important geophysical mass change and transport processes in the hydrosphere, cryosphere, ocean, and solid Earth at monthly intervals to a spatial resolution of 300–”
