SUMMARY The Gravity Recovery and Climate Experiment (GRACE) observes gravitational potential anomalies that include the effects of present-day surface mass change (PDSMC)- glacial isostatic adjustment (GIA)-driven solid Earth redistribution. Therefore, GIA estimates from a forward model are commonly removed GRACE to estimate PDSMC. There several models facilitate users in using their choice, bo...

The Arctic permafrost regions make up the largest area component of the cryosphere. Observations from the Gravity Recovery and Climate Experiment (GRACE) mission offer to provide a greater understanding of changes in water mass within permafrost regions. We investigate a GRACE monthly time series, snow water equivalent from the special scanning microwave imager (SSM/I), vegetation water content...

Considering the advantage of Empirical Mode Decomposition (EMD) for extracting geophysical signals and filtering out noise, this paper will first apply EMD approach to post-process Gravity Recovery Climate Experiment (GRACE) monthly gravity field models. A 14-year time-series Release 06 (RL06) models from Center Space Research (CSR) truncated degree order 60 period April 2002 August 2016 are an...

Abstract Gravity recovery and climate experiment (GRACE) GRACE Follow-On (GRACE-FO) are Earth’s gravity satellite missions with hydrological monitoring applications. However, caused by measuring instrumental problems, there several temporal missing values in the dataset of two where a long gap between mission also exists. Recent studies utilized different gap-filling methodologies to fill those...

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...
