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 output of CMIP6 EC-Earth3, experiment scenario ssp585 and the r1i1p1f1 ensemble member (EC-EARTH Consortium, 2019). This forcing dataset consists of near-surface atmospheric variables simulated by EC-Earth3 under the CMIP6 SSP585 scenario over 2015-2100. 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 from github and published on zenodo (Hayashida, H., 2021).
- `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 EC-Earth3, was derived from snowfall flux (prsn) and total precipitation (pr) summing rainfall and snowfall flux.
- the land ice calving flux (licalvf) is not available from EC-Earth3 so the original JRA55-do v1.4.0 values were prescribed for it.
This dataset was created by Dr Hakase Hayashida as part of the Centre of Excellence for Climate Extremes (CLEX) Climate variability and teleconnections research program.
