The data are in Excel spreadsheets and record cyanobacteria fluorescence, the presence of chlorophyll a and exocellular polysaccharide, soil surface strength, particle size distribution and soil loss by wind erosion. The study was located within Diamantina National Park (23°36’44.8”S; 143°17’46.9”E) in the north-eastern part of the Lake Eyre basin, central Australia. Site characteristics are 1/A physical depositional crust; 2/B cyanobacterial crust on dune flank; 3/D cyanobacterial crust on claypan; 4/E physical structural crust; 5/C cyanobacterial crust on nebkha field. Different amounts of rainfall were applied using Griffith University Mobile Rainfall Simulator (see Bullard et al. 2018 for technical details). Following rainfall and drying in situ of the surface, wind erosion was measured using a portable mini-wind tunnel (see Strong et al. 2016 for technical details). The data will be of value for understanding cyanobacterial response to different rainfall amounts and wind speeds under future climate scenarios.

Rainfall was applied (5 mm and 10 mm) to each site using a rainfall simulator. Before and after rainfall crust characteristics were measured. After soils had dried, but within 48 hours of rainfall the susceptibility of the soils to wind erosion was measured using a micro-wind tunnel. Where appropriate raw data are supplied for user-analysis. For the wind tunnel runs data are processed to indicate soil loss per run and summarised in a spreadsheet as wind tunnel requires proprietary software.
