Global climate fields for the early Cambrian simulated using the FOAM ocean-atmosphere general circulation model

These files contain the necessary data and R scripts for the manuscript "Quantitative comparison of geological data and climate simulations constrains early Cambrian geography and climate". The files include the NetCDF output of early Cambrian global climate simulations conducted using the coupled ocean-atmosphere FOAM general circulation model. The files include four hypothesized early Cambrian continental configurations, the topography-bathymetry files of which are also supplied. Global climate fields were simulated for each continental configuration at six greenhouse gas forcings: 4, 8, 16, 32, 64, and 128 times pre-industrial atmospheric level (PAL = 280 ppm). Simulations for all greenhouse gas forcings were run using present day orbital parameters. Additionally, there are cold and hot summer orbital parameter (CS and HS) and high and low obliquity orbital parameter (OH and OL) simulations at 32 PAL CO2. Also included is a compilation of lower Cambrian climatically sensitive lithologies. Finally, two R scripts  are included: one to convert the climate model outputs to Köppen-Geiger climate classes, and the other to quantitatively compare geological data and climate simulations. The reader is referred to the associated paper for a full description of the model boundary conditions, the lithology data, and the data-model comparison methods.
