This website provides the information regarding the input and output data of IAMIP2. For a full description, please refer to the protocol paper (Hayashida et al., 2021). For questions, email Hakase Hayashida (Institute for Marine and Antarctic Studies, University of Tasmania).

Input data for conducting IAMIP2 experiments

Historical (1958-2018)

The historical experiment is done by prescribing the following initial and boundary conditions. Click on the links below to download the data.

Projections (2015-2100)

There are four projections driven by the atmospheric outputs of two CMIP6 models (CMCC-ESM2, EC-Earth3) under two SSP scenarios (ssp126 and ssp585). These datasets are interpolated onto the JRA55-do grid and are available from the NCI Data Collection:

Atmospheric CO2 concentrations should be prescribed to the global and monthly mean values described by Meinshausen et al. (2017). These are available from the following website:

Exclusion (2015-2100)

The exclusion experiment is done in the identical setup as the historical experiment except that the sea-ice ecosystem component is excluded from the model.

Control (1958-2100)

The control run is done by applying the repeat-year forcing of JRA55-do v1.4.0 over 01/May/1990 – 30/April/1991. Please contact Hakase if you wish to obtain this data.
