This study focused upon the estimation and analysis of terrestrial water storage (TWS changes) across Canadian landscape. The was performed using Gravity Recovery Climate Experiment (GRACE) data from April 2002 to June 2017, GRACE Follow-On (GRACE-FO) observations 2018 December 2019. Removing gravity effects Glacial Isostatic Adjustment (GIA) signals leakage is required have realistic estimatio...

A new functional model is proposed for gravity field modeling on the basis of KBR data from the GRACE satellite mission. This functional model explicitly connects a linear combination of gravitational potential gradients with a linear combination of range-rate measurements at several successive epochs. The system of observation equations is solved in the least-squares sense by means of the pre-...

We carry out a comprehensive error assessment of Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-On (GFO) Release-6 (RL06) solutions from the Center for Space Research (CSR) at University Texas Austin, NASA Jet Propulsion Laboratory (JPL), Geoforschungszentrum (GFZ). The study covers period April 2002 to August 2020 uses two different methods, one based upon open ocean residuals (O...
