The indices offered through Climdex have been already calculated for several observational datasets. Although these source datasets are described as gridded analyses, we often offer data for the individual stations too. For the most up-to-date and quality-controlled dataset use HadEX3. If you need near-realtime data use GHCNDEX. HadEX2 is hosted here for comparison studies.
We offer time series for stations where available, whereas for gridded products we also offer average maps, trend maps and raw yearly data across any spatial domain. These products are variously available as text files, NetCDF files and image files.
Please remember to make appropriate reference to the linked publications when using these datasets.
Pre-computed Climdex indices for a number of climate models in the Coupled Model Intercomparison Project — Phase 3 (CMIP3) and Phase 5 (CMIP5) are available from Environment Canada.
