Experimental Data supporting the manuscript 'Synergistic Effects of Sea Surface Temperature and Sea Ice Concentration on the Extended-Range Predictability of the 2008 East Asian Extreme Cold Event'

The dataset includes model outputs from the OIFS experiments used in this study, comprising the control run (CTRL) and sensitivity experiments (ATE/BKS/ATE_BKS). ub_*/2t_*: geopotential height on 500 hPa/2m-temperature t_*/w_*/uv_*: temperature/vertical velocity/UV-component of wind on pressure levels.
