Annual Summaries of Heatwave Aspects in Europe, as defined by the Excess Heat Factor

The dataset includes six yearly time series of six Heatwave aspects/metrics calculated from the E-OBS dataset (v19eHOM, available in https://www.ecad.eu/download/ensembles/downloadversion19.0eHOM.php) following the Excess Heat Factor methodology implemented in the ClimPACT tool, considering the extended summer season (from June to September) and covering the European region.

Accordingly, each geodata file (GeoTIFF format, EPSG:4326) depicts a time series of a given type of annual statistical summary, comprising 69 bands from 1950 to 2018 (i.e., one per year). These heatwave annual aspects/metrics are as follows:

(i) annual Number of Heatwaves (HWN) - the annual sum of the number of heatwave events, in file 'ehf_eobs_e19HOM_1950-2018_reference_1961-1990_ann_hwn.tif';
(ii) annual Heatwave Days Frequency (HWF) - the annual sum of the number of heatwave days, in file 'ehf_eobs_e19HOM_1950-2018_reference_1961-1990_ann_hwf.tif';
(iii) annual Maximum Heatwave Duration (HWD) - the annual maximum length (in number of days) of the heatwave events, in file 'ehf_eobs_e19HOM_1950-2018_reference_1961-1990_ann_hwd.tif';
(iv) annual Mean Heatwave Magnitude (HWM) - the annual mean intensity of the heatwave events, in file 'ehf_eobs_e19HOM_1950-2018_reference_1961-1990_ann_hwm.tif';
(v) annual Maximum Heatwave Amplitude (HWA) - the annual maximum intensity of the heatwave events, in file 'ehf_eobs_e19HOM_1950-2018_reference_1961-1990_ann_hwa.tif';
(vi) annual Maximum Heatwave Severity (HWS) - the annual maximum severity of the heatwave events, in file 'ehf_eobs_e19HOM_1950-2018_reference_1961-1990_ann_hws.tif'.

These annual time series can be used in heatwave-related studies, particularly those focusing on climatology, trends and impacts on human health.
