Forward simulations of the Amundsen Sea Sector of West Antarctica at different resolutions produced from the ice sheet model WAVI

This dataset contains simulations produced by the ice sheet model WAVI (Wavelet-based Adaptive-grid Vertically-integrated Ice-model), presented as netCDF files. The model domain is the Amundsen Sea Sector of the West Antarctic Ice sheet, including Pine Island Glacier, Thwaites Glacier and the ice streams that flow into the Crossen and Dotson Ice Shelves. The simulations start from initialised states representing approximately the year 2015 and are run for 150 years into the future. The WAVI model is a publicly available open source model written in Julia (Bradley et al., 2024). The initialised states are computed in the Matlab version of WAVI, following methods in Arthern et al. (2015) and Arthern and Williams (2017). These simulations were produced by the authors to study the effects of spatial model resolution and basal melt rates on projections of sea level contribution from this region.

Funding was provided by NERC Feasibility Study Grant (Ref: 2021DTUC3Hosking) and ITGC THHWAITES-MELT (NE/S006656/1).

Statement: The initialisation algorithm used was evaluated on idealised test cases as described by Arthern and Gudmundsson (2010). Arthern et al (2015) shows maps of discrepancy between model velocity and satellite derived velocity, and histograms of the differences between model elevation changes and elevation changes derived using satellite altimetry. The WAVI.jl package has standard tests to check the performance of the code. These are documented in WAVI.jl/test. A value of -9999 indicates there are no data there.
