Full description

This dataset provides the atmospheric forcing fields for conducting the projection experiment for the Ice Algae Model Intercomparison Project phase 2 (IAMIP2), which is a new model intercomparison effort focused on algae that are attached to sea ice.

It is based on the first ensemble member (r1i1p1f1) output of the three CMIP6 projections: CMCC-ESM2 ssp126, EC-Earth3 ssp126, CMCC-ESM2 ssp585. These complement the EC-Earth3 ssp585 based forcing previously published as 'EC-Earth3 SSP585 atmospheric forcing dataset for the Ice Algae Model Intercomparison Project phase 2 (IAMIP2) projection experiment v1.0', in this same collection. Each dataset contains the near-surface atmospheric variables for driving the sea ice-ocean coupled models over 2015-2100, prepared for the projection experiment of the Ice Algae Model Intercomparison Project phase 2 (IAMIP2). The dataset is interpolated to the JRA55-do v1.4 grid (Tsujino, H. and al., 2018), to make it easy for using it in ocean and sea-ice models. 

This dataset is a global product of 0.5-degree resolution near-surface atmospheric variables over the period 2015-2100. The variables included in the dataset are:

tas - surface air temperature

vas - surface northward wind 

uas - surface eastward wind 

huss - surface specific humidity

licalvf - land ice calving flux

psl - sea level pressure

rsds - surface downwelling shortwave radiation flux

rlds -surface downwelling longwave radiation flux

friver - water flux into sea water from rivers 

prra - rainfall flux

prsn - snowfall flux

The code to interpolate JRA55-do v1.4 is available on github and published on zenodo (Hakase H., 2021)

In particular:

  • `cdo -remapnn` was used for the river runoff into sea water (friver) variable and `cdo -remapcon` for all others. 
  • rainfall flux (prra), which is not available from CMCC-ESM2 and EC-Earth3, was derived from snowfall flux (prsn) and total precipitation (pr)  
  • the land ice calving flux (licalvf) is not available from CMCC-ESM2 and EC-Earth3 so the original JRA55-do v1.4.0 values were prescribed for it.
