Abstract
This dataset includes model output from a forced ocean-ice simulation to document the impact of sea ice physics and atmospheric forcing data on the Arctic sea ice evolution produced for the The North Atlantic Climate System Integrated Study (ACSIS). This uses the same sea ice model CICE configuration GSI8.1 (Ridley et al., 2018) with an atmospheric forcing data set are applied: NCEP Reanalysis-2 (NCEP2) data (Kanamitsu et al., 2002, updated 2020). Regarding the sea ice component, we use the default CICE setup as in HadGEM3 (CICE-default) and an advanced setup (CICE-best) in which a new process is added (snow loss due to drifting snow) and some adjustments have been made to model physics and parameters.
The specific parameters for this dataset are:
sea ice model: CICEv5.1.2 with prognostic melt pond model and EAP rheology, but with several modifications including snow drift scheme, bubbly conductivity scheme, increased sea ice emissivity and reduced melt pond max fraction parameter (see Schroeder et al., TC 2019)
ocean model: NEMOv3.6
period: 1960-2015
atmospheric forcing: NCEP2
domain: global
grid resolution: 1deg ORCA
The simulation was performed by the Centre of Polar Observation and Modelling (CPOM) at University of Reading under the ACSIS project. ACSIS was funded by the Natural Environment Research Council (NERC) through National Capability Long Term Science Multiple Centre (NC LTS-M) grant NE/N018028/1.

| Title | Computation for Global ocean-ice and pan-Arctic sea ice simulations with different sea ice physics and atmospheric forcing data sets |
| Abstract | 6 forced ocean-ice simulations and 2 stand-alone ice simulations to document the impact of sea ice physics and\ \ atmospheric forcing data on the Arctic sea ice evolution. All of them use the\ \ same sea ice model CICE configuration GSI8.1 (Ridley et al., 2018) and the ocean-ice\ \ ones the same ocean model NEMO GO6.0 (Storkey et al., 2018) as HadGEM3. Three\ \ different atmospheric forcing data set are applied: NCEP Reanalysis-2 (NCEP2)\ \ data (Kanamitsu et al., 2002, updated 2020), CORE II surface data (Large & Yeager,\ \ 2009) and the atmospheric forcing data set DFS5.2 (Dussin et al., 2016). Regarding\ \ the sea ice component, we use the default CICE setup as in HadGEM3 (CICE-default)\ \ and an advanced setup (CICE-best) in which a new process is added (snow loss due\ \ to drifting snow) and some adjustments have been made to model physics and parameters.\ \ \n\nThe simulations were performed by the Centre of Polar Observation and Modelling\ \ (CPOM) at University of Reading under the ACSIS project |
