Description: Data supporting the publication Hornby, AJ, Kueppers U, Maurer BM, Poetsch C and Dingwell DB (2020) "Experimental constraints on volcanic ash generation and clast morphometrics in pyroclastic density currents and granular flows". In this study, fine ash is generated from lapilli-sized volcanic pumice and scoria in rotary tumbler experiments. We seek to explore ash production processes and clast attrition in natural PDCs, and gain insight into the controlling parameters for particle production efficiency with PDC transport distance. We vary the starting mass, apparatus size, and material properties and tumble clasts over multiple transport distance steps from 0.2-6 km. The data are provided in ASCII or image formats as one zipped folder (2020-025_Hornby-et-al_data.zip) and organised in the following sub-folder structure (for more information please consult the associated data description and Hornby et al (2020): (1) Experimental methods, apparatus and data collections (2) Ash generation data for tumbling experiments (3) Laser particle size distribution data for ash generated in tumbling experiments (4) Post-experimental lapilli size (generated via 3-axis caliper measurements), mass, bulk density and dense rock equivalent (DRE) porosity results (5) 2D image analysis morphology results (6) 2D image analysis size results (7) Cropped, scaled and thresholded images lapilli used for morphometric analysis (8) Image analysis macros and workflow for ImageJ (9) Integrated analysis of results This project has received funding from the European Union's Horizon 2020 research and innovation programme.
