Comparison Metrics for ERA5 against in situ observations in the Arctic
<p>The comparison metrics (R2, slope, RMSE, Pearson correlation coefficient) were produced from a comparison between the ERA5 reanalysis model and in situ observations from ground-based stations in the Arctic. The datasets accompany the manuscript "Comparison of selected surface level ERA5 variables against in situ observations in the Arctic" by Pernov et al. (2023). The Excel files are located in three sub-folders (All, Seasonal, and Temporal). Each variable has its own Excel file. The sub-folder "All" gives the metrics when using all available data from each station at a 1-hour temporal resolution. The sub-folder "Seasonal" gives the metrics when the comparison is made on a seasonal basis, with sub-folders indicating the season. The sub-folder "Temporal" gives the metrics when comparing different temporal resolutions, which are indicated in the sub-folders. </p> <p>For questions, please contact jakob.pernov@epfl.ch or julia.schmale@epfl.ch</p>

Preparatory Process in Advance of Runaway Fault Rupture through Fluid Injection observed in Laboratory Experiments using a Large Specimen of Sub-meter scale
<p>Fault slip is initiated by locally applied fluid pressure, and it can expand unstably over a wide area causing elastic waves having magnitudes that induce felt or destructive earthquakes. Thus, it is important to examine the unstable expansion of initial slips. However, it is hard to reproduce the process by general setup of laboratory experiment such as triaxial loading tests on cylindrical specimens with inclined faults. In this study, we prepared a cubic specimen of sub-meter scale, which was separated into two triangular prisms by a model fault. The specimen was subjected to bi-axial compressions with different magnitudes. A 2D array of strain gauges was embedded beneath the fault plane to measure the changes in shear strain with the fault slip driven by fluid injection. Based on the experimental results, we discussed the features of fault slips that lead to injection-induced earthquake. The dataset obtained by the experiments were presented in the current data repository.</p>
