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

The raw, pre-processed, and modeled 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>). The original GNSS time-series are F5 solutions, which are distributed by Geospatial Information Authority of Japan (GSI, https://www.gsi.go.jp/). The details and availability of F5 solutions are written in Takamatsu et al. (2023, Earth, Planets, and Space) https://doi.org/10.1186/s40623-023-01787-7. 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 postseismic deformation of the 2011 Tohoku earthquake, the Boso SSEs, and postseismic deformations due to aftershocks and L-ASE (long-term aseismic slip event) since late 2019.<br> <br> "sitelist.txt" - 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] <br> <br> "pre-process/xxxx.txt" - Time-series at xxxx (4digits site ID) site<br> column 1: days from Mar. 12, 2011 (1 corresponds to Mar. 12, 2011)<br> column 2: raw East-West displacement [m]<br> column 3: raw North-South displacement [m]<br> column 4: raw Up-down displacement [m]<br> column 5: pre-processed East-West displacement [m]<br> column 6: pre-processed North-South displacement [m]<br> column 7: pre-processed Up-down displacement [m] "model/xxxx/prediction_yy.txt" - Time-series for yy component (yy=EW, NS, UD) at xxxx (4digits site ID) site<br> column 1: days from Mar. 12, 2011 (1 corresponds to Mar. 12, 2011)<br> column 2: modeled displacement excluding the Boso SSEs [m]<br> column 3: modeled displacement excluding the Boso SSEs and postseismic deformation due to aftershocks caused one year after the 2011 Tohoku Eq.

The raw time-series excluded outliers from the original F5 solutions, and the raw time-series were transformed into the Okhotsk plate reference.
