Deep Learning Models Ratify ENSO's Substantial Impact on Antarctic Sea Ice Subseasonal Predictability: supplemental data

cor_spatial38c.hdf contains SIPNet skill information, comprising four subsets: 'mid', 'nino', 'nina', and 'all', representing model skill under neutral conditions, El Niño, La Niña, and the entire time range, respectively.

acc_per_spatial38.hdf is similar to cor_spatial38c but represents the model skill for anomaly persistence.

cor_spatial38_linear.hdf, like cor_spatial38c, represents the model skill but specifically for the linear SIPNet model.

sic_stddev.hdf contains sea ice variability information with three subsets: 'nino', 'mid', and 'nina', denoting sea ice variability under El Niño, neutral conditions, and La Niña, respectively.

t2m_composite38.hdf: Surface air temperature composite dataset, containing composites for four seasons.

sst_composite38.hdf: Similar to t2m_composite38, but for sea surface temperature.

mslp_composite38.hdf: Similar to t2m_composite38, but for sea level pressure.

obser_sic_composite.hdf: Similar to t2m_composite38, but for observed sea ice concentration.

predi_sic_composite.hdf: Similar to t2m_composite38, but for predicted sea ice concentration.
