Data contains raw output of experiments with a new Eulerian iceberg module coupled to MPI-OM and MPI-ESM. Experiments in a coupled MPI-OM-Iceberg setup evaluate iceberg size classes representation. MPI-ESM-Iceberg experiments allow to understand how different treatment of calved from ice sheet ice (as icebergs or icebergs without accounting for latent heat, freshwater released in one point or distributed within a latitude belt) results in different climate response.
