ERA5 data by Canadian hail event 2005-2022

<p>This dataset is in HDF5 format. The data was pulled from the ECMWF reanalysis datasets "<a href="https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels?tab=overview"><strong>ERA5 hourly data on single levels from 1940 to present</strong></a>" and "<a href="https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-pressure-levels?tab=overview"><strong>ERA5 hourly data on pressure levels from 1940 to present</strong></a>."&nbsp;</p><p>Each file in "era5_by_canadian_hail_event" is associated to a specific Canadian hail event and combines the relevant data from both ERA5 datasets. The hail events were created based on the 7000 Canadian hail reports contained in "<a href="https://zenodo.org/records/8015925">Integrated Canadian Hail Database (2005-2022)</a>", where we considered reports to be of the same event if they were within a specified window in time and space (7 hours by 256 km). The 7000 reports were grouped into 2092 hail events. Thus, our ERA5 based dataset <strong>contains 2092 files</strong>.
