<dct:description><p>Data on two tomographic studies on Berea sandstone as supplemental information of the publication &quot;Flow field tomography of reactive transport: comparison of &beta;⁺ tracers &sup1;⁸F, ⁷⁶Br &amp; &sup1;&sup2;⁴I&quot; by Jann Sch&ouml;ngart, Johannes Kulenkampff, and Cornelius Fischer<em>. </em></p> <p>Part of the data published here was used for prior works by <a href="https://doi.org/10.1016/j.jhydrol.2025.133868">Schabernack et al. (2025)</a>. Therefore, the the presented dataset has overlap withthe dataset published in&nbsp;<a href="https://doi.org/10.14278/rodare.3126">Kulenkampff et al. (2024)</a>. This overlap is limited to the&nbsp;&micro;CT data, and the PET data for analysis D_B and D_C.</p> <p>The data in this publication consists of:<br> <br> <strong>&micro;CT data</strong></p> <p>Core_D_after_dissolution_2496x2496x1615.raw:&nbsp; &micro;CT of the inlet section of berea sandstone core D before dissolution as normalized graylevel data, voxel size = 10.032 &micro;m. Format: 3D-array of uInt16, x=1:2496, y=1:2496, z=1:1615.</p> <p>Core_D_before_dissolution_2307x2329x1452_uint16.raw:&nbsp;&micro;CT of the inlet section of berea sandstone&nbsp;core D after dissolution as normalized graylevel data, voxel size = 10.032 &micro;m. Format: 3D-array of uInt16, x=1:2307, y=1:2329, z=1:1452.</p> <p><strong>Positron emission tomography data<br> All PET data is stored as three-dimensional binary arrays of floats, with a voxel size of 1.15 mm.</strong></p> <p>Stored in [subset]_PET_raw.zip:&nbsp;</p> <p>Uncalibrated positron emission tomography time series (decay corrected). Each image consists of two files - a header file (.hv) and the binary image file (.v). The header file contains information on how to read the binary file, as well as additional information.&nbsp;<br> Please note that not all of the metadata given in the header file (like timestamps, etc.) are generated automatically and not neccessarily accurate.</p> <p>Stored in [subset]_PET_err.zip:&nbsp;</p> <p>Relative errors of the PET_raw data, calculated from count rates using poisson statistics. A value of 1 equals 100% error. The volumes are cut to the ROI.&nbsp;The data structure is identical to&nbsp;[samplename]_PET_raw.zip.</p> <p>Stored in [subset]_PET_corrected.zip:&nbsp;</p> <p>Positron emission tomography time series, corrected for tracer activity and detector sensitivity fluctuations. Values are in in Bq/voxel. Voxels with relative errors above 100% are discarded. The volumes are cut to the ROI.&nbsp;The data structure is identical to&nbsp;[samplename]_PET_raw.zip.</p> <p><strong>Flow field data</strong><br> stored in [subset]_flowfield.zip:&nbsp;<br> Flow Direction_[X]x[Y]x[Z]x1_vec3_double.raw: Flow direction vectors as binary data of the shape [x,y,z,[3]], a three dimensional array of vectors which are stored as double (float64), &nbsp;voxel size = 1.15 mm.</p> <p>Flow Rate_[X]x[Y]x[Z]x1_double.raw: Flow rates (uncalibrated)&nbsp;as binary data of the shape [x,y,z], a three dimensional array of doubles (float64), &nbsp;voxel size = 1.15 mm.</p> <p>Porosity_[X]x[Y]x[Z]x1_double.raw:&nbsp;Porosities (uncalibrated)&nbsp;as binary data of the shape [x,y,z], a three dimensional array of doubles (float64), &nbsp;voxel size = 1.15 mm.</p> <p>Transport Error_[X]x[Y]x[Z]x1_double.raw: A measure of error quantifying the ratio of computed in- and outflow to each voxel. Values close to 0 are better. Stored as binary data of the shape [x,y,z], a three dimensional array of doubles (float64), &nbsp;voxel size = 1.15 mm.</p> <p>Velocity_[X]x[Y]x[Z]x1_double.raw: Velocities&nbsp;(uncalibrated)&nbsp;as binary data of the shape [x,y,z], a three dimensional array of doubles (float64), &nbsp;voxel size = 1.15 mm.</p></dct:description>
