SSW-Type Composite 1000 hPa Temperature Anomalies over Scandinavia/Northern Europe (1957–2013)
This dataset was generated for Choi et al. (2021) using NCEP/NCAR reanalysis 1000 hPa temperature data (Kalnay et al., 1996) from 1 July 1957 to 30 June 2013. It provides composite mean values of the 3-day running-mean 1000 hPa temperature anomaly, averaged over Scandinavia/Northern Europe (40E-40W, 60N-75N) for each SSW type (DD, DS, SS). The dataset includes 61 daily values from day –30 to day +30 relative to the SSW onset date. Anomalies are defined relative to the 1981–2010 climatology. SSW types follow the classification of Choi et al. (2019), and the associated dataset is available in KPDC (KOPRI-KPDC-00003036). Choi, H., Kim, B. M., & Choi, W. (2019).
