ISMIP7 Antarctic Ocean Melt Calibration

Name: ISMIP7 Antarctic Ocean Melt Calibration
Creator: ISMIP

Data for calibrating sub-ice-shelf melt parameterisations for ISMIP7 Antarctic experiments: ocean model output, hydrographic observations, observational estimates of melt rates, buttressing flux response numbers, drainage basins and ice-shelf masks, and the meltMIP intercomparison inputs. Third-party model output and observations from several groups, each with its own citation and licence — see the per-dataset attribution in the product README.

Observed basal melt rates

Melt_Paolo_Davison_Adusumilli_imbie2.csv gives the observed basal melt rate and its uncertainty per IMBIE2 basin, combining three satellite-derived melt-rate products; melt_target_term2_v3.nc is the calibration target derived from it by the ISMIP7 AIS ocean focus group.
