Global Distribution of Frost Cracking Intensity during Late Cenozoic Time-slices

This dataset includes the first order (global) distribution of frost cracking intensities (FCI) [°C m], for selected paleoclimate time-slices during Late Cenozoic, as presented in the paper by Sharma et al. (2022). The paleoclimate time-slices correspond to Pre-Industrial (~1850 CE, PI), Mid-Holocene (~6 ka, MH), Last Glacial Maximum (~21 ka, LGM) and Pliocene (~3 Ma, PLIO). The FCI (by segregation ice growth) is predicted using the approach of Andersen et al. (2015), as a function of subsurface thermal gradient and volume of (and distance to) liquid water. The paleo-temperature reconstructions are obtained from ECHAM5 general circulation model (GCM) at T159 spatial resolution (80 km * 80 km) by Mutz et al. (2018). The spatial resolution of FCI dataset is same as ECHAM5 GCM simulations (i.e. 80 km * 80 km). The dataset comprises the following: - Scripts (Python) for modeling FCI for approach described in Sharma et al. (2022). - Global FCI distribution as netCDF and ascii formats. The data is available in both netCDF and ascii formats. However, the model code (attached Python scripts) currently supports only netCDF format. The model scripts can be freely utilized for regional and local studies which require finer resolution dataset. Please refer to the associated data description file for a detailed description of the dataset.
