Data on a tomographic study of leaching processes on a Berea sandstone as supplemental information of the publication "Coupled dissolution and clogging processes alter the fluid flow field in sandstones beyond the pore scale" by Jonas Schabernack, Johannes Kulenkampff, and Cornelius Fischer, to be submitted to Earth and Planetary Science Letters (https://www.sciencedirect.com/journal/earth-and-planetary-science-letters).

The data consists of 

1. BA6_312h_Concentration_65x65x66x40_double.raw: Time dependent activity concentrations (MBq/voxel) derived from 40 PET frames with frame length = 300 s, voxel size = 1.15 mm, measurement after a leaching period of 312h. Format: 4D-array of double, x=1:65, y=1:65, z=1:66, t:1:40.
2. BA6_1320h_Concentration_65x65x61x40_double.raw: Time dependent activity concentrations (MBq/voxel) derived from 40 PET frames with frame length = 300 s, voxel size = 1.15 mm, measurement after a leaching period of 1320h. Format: 4D-array of double, x=1:65, y=1:65, z=1:61, t:1:40.
3. BA6_312h_Flow Rate_65x65x66x1_double.raw: Magnitude of flow rate (mm³/s) from flowfield reconstruction of 1. Format: 3D-array of double, x=1:65, y=1:65, z=1:66.
4. BA6_1320h_Flow Rate_65x65x61x1_double.raw: Magnitude of flow rate (mm³/s) from flowfield reconstruction of 2. Format: 3D-array of double, x=1:65, y=1:65, z=1:61.
5. BA6_mag_1_01.raw.corrected.view.raw: µCT of the inlet section before leaching as normalized graylevel data, voxel size = 10.032 µm. Format: 3D-array of UInt16, x=1:2446, y=1:2450, z=1:1852. 
6. BA6_mag_1_after_10u_01_to_befor.diff.view.raw: difference image of matched graylevels after-before leaching, voxel size = 10.032 µm. Format: 3D-array of (signed) Int16, x=1:2446, y=1:2450, z=1:1852.
