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
