NAHosMIP - monthly surface air temperature and precipitation v3

This dataset is for data generated from the North Atlantic Hosing Model Intercomparison Project (NAHosMIP), which is documented in Jackson et al, 2023. 

Data used in that paper (including AMOC streamfunctions) can be found here 

Experiments

picon - preindustrial control which was run as part of CMIP6 (Eyring et al., 2016),

u03-hos - constant uniform hosing of 0.3 Sv. 

u03-r50 - experiment with no hosing initialised 50 years into u03-hos

u03-r100 - experiment with no hosing initialised 100 years into u03-hos

Models

Eight CMIP6 models took part: CanESM5, CESM2, EC-Earth3, HadGEM3-GC3-1LL, HadGEM3-GC3-1MM, IPSL-CM6A-LR, MPI-ESM1-2-HR, MPI-ESM1-2-LR  

Variables

tas - surface air temperature (monthly resolution)

pr - precipitation (monthly resolution)

evspsbl - surface evaporation (including sublimation and transpiration)

psl - sea level pressure

File name convention

We use the CMIP file naming convention, so for example:

tas_Amon_HadGEM3-GC31-LL_u03-r100_r1i1p1f1_gn_215001-215912.nc

$variable_$timeresolution_$model_$experiment_$version_$grid_$date.nc

Files with the same variable and model are combined in a tar file:

$variable_$timeresolution_$model_$version_$grid.tarAMOC timeseriesThese are included in the file M26.tar. This is the maximum streamfunction at 26.5NAdditional precip and wind filesAlso included are files used by Ben-Yami et al, 2024 who examined the impacts of an AMOC collapse on monsoons. The files contain monthly mean (mmean) or annual mean (ymean) of precipitation (prcp) and surface winds (ua and va) for the experiments u03-r50 (for HadGEM3-GC31-MM, CanESM5, CESM2) or u03-r100 (for IPSL-CM6A-LR)Files are named
