Hourly values of an advanced human-biometeorological index for diverse populations from 1991 to 2020

The presented human thermal bioclimate dataset was created in the frame of the HEAT-ALARM ("Development of a heat-health warning system in Greece") research project. It consists of hourly values of population-weighted mPET (modified physiologically equivalent temperature), simulated by the RayMan Pro model for the period 1991-2020 and for six population subsets in 72 regional units and combinations thereof, which are based on the NUTS-3 (Nomenclature of Territorial Units for Statistics-3) classification in Greece, using the Copernicus European Regional Reanalysis (CERRA) at 5.5 km spatial resolution. The code used to produce the presented data is available at: https://doi.org/10.5281/zenodo.8009730. It can be used to replicate the dataset not only directly in Greece, but also in any other country included in the CERRA domain after appropriate adjustments.
