This is the download page for aggregated station indices data for all stations within ECA&D. Indices data are freely available for non-commercial research. For each station
indices are calculated, each describing changes in the mean or extremes of climate.
indices follow the definitions recommended by the CCl/CLIVAR/JCOMM Expert Team on Climate Change Detection and Indices (ETCCDI, marked with *). To learn more about the indices and the way they are calculated see the Indices dictionary.
The 75 indices have been grouped in different categories corresponding with different aspects of climate change.
There is one datafile for each index. Each datafile gives information for all available stations in the ECA&D database. The indices are aggregated over the year, the winter-half (ONDJFM), the summer-half (AMJJAS), winter (DJF), spring (MAM), summer (JJA), autumn (SON) and each of the calendar months. This readme file gives more information.
