MISOMIP2's perturbation MIPkit See the article describing the protocol . Atmospheric forcing perturbation (for the *-warm experiments) Atm_*_anomaly_MISOMIP2.nc These data are described in Mathiot and Jourdain (2023) and were initially provided on https://doi.org/10.5281/zenodo.8139775 . They correspond to the monthly anomaly of the 2260-2299 mean (SSP5-8.5) with respect to the 1975-2014 mean (historical) in member r1i1p1f1 of the IPSL-CM6-LR simulations ( Boucher et al., 2020 ). The anomalies to add to the present-day reanalysis forcing in MISOMIP2's *-warm experiments are provided as 3-hourly annual climatologies on the JRA55 lon-lat grid for the following variables: dhuss : Near-Surface Specific Humidity anomaly. dpr : Precipitation anomaly at surface; includes both liquid and solid phases from all types of clouds (both large-scale and convective). dprsn : Solid precipitation anomaly at surface; includes precipitation of all forms of water in the solid phase. dps : Surface Air Pressure anomaly. drlds : Surface Downwelling Longwave Radiation anomaly. drsds : Surface Downwelling Shortwave Radiation anomaly. dtas : Near-Surface Air Temperature anomaly. duas : Eastward Near-Surface Wind anomaly. dvas : Northward Near-Surface Wind anomaly. The anomalies are provided for a 365-day year. If the present-day forcing used in MISOMIP2 contains leap years, then the 28-February forcing should be repeated on February 29th. Ocean forcing perturbation (lateral boundary conditionsfor the *-warm experiments) Ocean_p_*_climatology_MISOMIP2.nc and Ocean_vw_*_climatology_MISOMIP2.nc These files are needed to prescribe an anomaly at the lateral boundaries of regional ocean and sea-ice models in the *-warm experiments. The data come from the global 0.25° NEMO simulations described in Mathiot and Jourdain (2023) , including a simulation forced by the aformentioned perturbation of the atmospheric forcing. Given that the method to do this is open and may be done either in the physical space or in the (T,S) space, we provide both the ...
