This dataset contains the data and scripts for the publication "Emulating present and future simulations of melt rates at the base of Antarctic ice shelves with neural networks" in Journal of Advances in Modeling Earth Systems . Before going into details, here is a reminder that the NEMO runs for the training dataset are called 'OPM+number'. These are the corresponding names given in the manuscript: OPM006=HIGHGETZ, OPM016=WARMROSS, OPM018=COLDAMU and OPM021=REALISTIC. For the testing dataset: 'bf663' is the REPEAT1970 run and 'bi646' is the 4xCO2 run. Most of the formatting and preprocessing of the training data has been made for Burgard et al. 2022 . The raw and to-some-degree processed data can therefore be found here: https://doi.org/10.5281/zenodo.7308352 . The raw data for the testing dataset is from Smith et al. 2021 , you can find it here: https://doi.org/10.5281/zenodo.7886986 The following folders and files can be found here: =============== raw/ Some geometrical files needed for initial data formatting and masking. =============== interim/ ANTARCTICA_IS_MASKS / ( from INTERIM_ANTARCTICA_IS_MASKS.zip ): contains masks and geometric information for the testing dataset to be included in the input file of the neural network and for the classic parameterisations. local bedrock and ice meridional and zonal slopes BOXES/ ( from INTERIM_BOXES.zip ): contains variables needed to apply the box parameterisation for the testing dataset PLUMES/ ( from INTERIM_PLUMES.zip ): contains the variables needed to apply the plume parameterisation for the testing dataset SMITH_bf663/ and SMITH_bi646/ ( from INTERIM_SMITH*.zip ): for testing dataset, corrected_draft_bathy_isf.nc: file containing ice draft and bathymetry corrected by ice draft concentration to account for the biased draft and bathymetry at the grounding line resulting from the interpolation from the native NEMO grid to the stereographic grid (values under ice shelf and NaNs over land custom_lsmask_Ant_stereo_clean.nc: land-sea mask giving 0 = ocean, 1 = ...
