Extreme Temperature Indices Time Series - Yearly summary ET-SCI Indices calculated from E-OBS v17.e dataset, with ClimPACT2 software at 5 Southern European Cities

The whole time span available at the time of the study was considered (from 1950 up to September 2018), and only Athens had fewer data available, with time series ending on 2005. The study focuses on 22 sector-relevant extreme temperature indices, from the Expert Team on Climate Risk and Sector-specific Indices (ET-SCI), all calculated on a yearly basis, using the R-based ClimPACT2 tool (Alexander and Herold 2016). The time series data was subject to quality control (QC), the first step in using the ClimPACT2 software, as instructed in the respective User Guide (Alexander and Herold 2016).

After QC assessment, reported errors were manually checked, and replaced with null values (missing data). Afterwards, missing data percentage was assessed, assuring it to comply with the World Meteorological Organization recommendations (WMO 2016): missing data percentage was below the 0.05% level, on every case. Please note that the data here presented corresponds to an earlier version of the dataset mentioned in the following articles: Oliveira et al. (2022a: doi:10.1016/j.dib.2022.108511) and Oliveira et al. (2022b: doi:10.1016/j.wace.2022.100455).
