Pre-processed and modeled GNSS time-series after the 2011 Tohoku Earthquake

<p>The raw, pre-processed, and modeled&nbsp;GNSS time-series of the 213 GEONET sites in the Tohoku region, Japan, from Mar. 12, 2011 to Nov. 20, 2021, relative to the Okhotsk plate (Argus et al., 2011, <em><em>Geochemistry, Geophysics, Geosystems</em></em>).</p> <p>The original GNSS time-series are F5 solutions, which are distributed by&nbsp;Geospatial Information Authority of Japan (GSI,&nbsp;https://www.gsi.go.jp/). The details and availability of F5 solutions are written in Takamatsu et al. (2023, Earth, Planets, and Space)&nbsp;https://doi.org/10.1186/s40623-023-01787-7.</p> <p>The GNSS time-series processing was performed by Tomita (submitted), and the following signals were excluded from the raw time-series: seasonal variation, coseismic step, antenna maintenance offset, and common mode errors. Then, the pre-processed time-series were modeled by a trajectory modeling method considering&nbsp;postseismic deformation of the 2011 Tohoku earthquake, the Boso SSEs, and&nbsp;postseismic deformations due to aftershocks and L-ASE (long-term aseismic&nbsp;slip event) since late 2019.<br> <br> &quot;sitelist.txt&quot; - Site information file<br> column 1: Full site ID<br> column 2: 4digits site ID<br> column 3: Longitude [deg]<br> column 4: Latitude [deg]<br> column 5: Height [m]&nbsp;<br> <br> &quot;pre-process/xxxx.txt&quot; - Time-series at xxxx (4digits site ID) site<br> column 1: days from&nbsp;Mar. 12, 2011 (1 corresponds to Mar. 12, 2011)<br> column 2: raw East-West displacement [m]<br> column 3: raw North-South&nbsp;displacement [m]<br> column 4: raw Up-down&nbsp;displacement [m]<br> column 5: pre-processed&nbsp;East-West displacement [m]<br> column 6: pre-processed&nbsp;North-South&nbsp;displacement [m]<br> column 7: pre-processed&nbsp;Up-down&nbsp;displacement [m]</p> <p>&quot;model/xxxx/prediction_yy.txt&quot; - Time-series for yy&nbsp;component (yy=EW, NS, UD) at xxxx (4digits site ID) site<br> column 1: days from&nbsp;Mar. 12, 2011 (1 corresponds to Mar. 12, 2011)<br> column 2: modeled&nbsp;displacement excluding the Boso SSEs [m]<br> column 3: modeled&nbsp;displacement excluding the Boso SSEs and&nbsp;postseismic deformation due to aftershocks caused one year after the 2011 Tohoku Eq.

Moreover, the cumulative displacement field due to the 2019 L-ASE since Nov. 25, 2019 was also calculated.&nbsp;In those files, the estimation errors are also shown as 1&sigma; standard deviation obtained from diagonal components of the model covariance matrices.&nbsp;</p> <p>&nbsp;</p> <p>The details of these data are introduced in the corresponding paper (Tomita, submitted).</p>
