For 15 years, the Gravity Recovery and Climate Experiment (GRACE) mission have monitored total water storage (TWS) changes. The GRACE ended in October 2017, 11 months later, Follow-On (GRACE-FO) was launched May 2018. Bridging gap between both missions is essential to obtain continuous mass To fill gap, we propose a new approach based on remove–restore technique combined with an autoregressive (AR) prediction. We first make use of Global Land Data Assimilation System (GLDAS) hydrological...
The character of the topocentric components in ETRF2000(R08) from Polish ASG-EUPOS system was analysed using skewness and kurtosis derived data probability density function. 115 permanent GPS stations with a time span more than 5 years were used. main goal this research to show that any unmodelled systematics can disrupt results. obtained median values clearly indicate discrepancies between assumed normality series distribution reality, mainly due stochastic and/or deterministic parts are...
Abstract The goal of this paper is to determine and analyze the common geocenter signal from coordinates based on four independent techniques: Doppler Orbitography Radiopositioning Integrated by Satellite (DORIS), Global Navigation System (GNSS), Gravity Recovery And Climate Experiment with ocean bottom pressure model, Laser Ranging, residuals as differences between these their signal. Another objective compute variable amplitudes phases annual semi-annual oscillations in techniques...
Abstract Earth’s crust deforms in various time and spatial resolutions. To estimate them, geodetic observations are widely employed compared to geophysical models. In this research, we focus on the deformations resulting from hydrology mass changes, as observed by GRACE (Gravity Recovery Climate Experiment) gravity mission modeled using WGHM (WaterGAP Global Hydrological Model) GLDAS (Global Land Data Assimilation System), hydrological We use newest release of Level-2 products, i. e. RL06,...

Abstract Sub-seasonal variations and especially sub-seasonal oscillations with periods of about 120, 60, 50, 40 days in polar motion 60–90, 50 LOD are presented. Variations amplitudes these shown. Maxima the order 2–4 mas. These elliptical ones. The correlation coefficients between geodetic atmospheric excitation functions this range spectrum variable have annual variations. 0.6–0.8. Modern VLBI experiments provide very accurate results UT1–UTC a temporal resolution 3–7 minutes. Several...
the US Naval Observatory together with Space Research Centre in Warsaw initiated Earth Orientation Parameters Combination of Prediction Pilot Project, which was accepted by IERS Directing Board.The goal this project is to determine feasibility combining (EOP) predictions on an operational basis.The ensemble EOPs are more accurate than results from individual predictions.The pole coordinate data different prediction contributors and computed U.S. studied statistical properties polar motion...
It has been reported previously that the filtered semiannual oscillation (SAO) of polar motion a variable amplitude modulated with period about 3 years. Assuming, this quasi 3‐year modulation is caused by beat two oscillations, namely SAO and semi‐Chandler (SCHO), we them using Fourier Transform Band Pass Filter (FT BPF) carefully choosen parameters. These oscillations from astrometric set data IERS (90C04) combined have slightly amplitudes 11 to 13 years reaching maxima several mas. Similar...
