| Result | kpdc_SH_SPV_weakening_onset_dates_ERAI_1979-2017_v1.csv | This dataset provides onset dates of Southern Hemisphere stratospheric polar vortex (SPV) weakening events. The dataset was generated using ERA-Interim reanalysis geopotential height fields and follows the event identification framework applied in Kwon et al. (2020). The file is formatted as a simple table and includes, for each event, the Year, Month, Day, and the corresponding Day of Year (DOY). | 274 Bytes | Request required |
