Exposure datasets for the paper "Heat metrics and thresholds reshape population exposure and inequality signals"

This repository contains the processed heat-exposure datasets supporting the paper “Heat metrics and thresholds reshape population exposure and inequality signals”. The dataset includes country-level 1 km raster outputs of heat-exposure metrics across the Mediterranean region, organized by heat metric and threshold framework. Heat metrics include land surface temperature (LST), air temperature (Ta), heat index (HI), and wet-bulb globe temperature (WBGT). Threshold frameworks include absolute and relative definitions of extreme heat. In the dataset, folders with names containing “Exposure” correspond to exposure duration (person-days), whereas folders containing “CumExposure” correspond to exposure density (person-day-degrees). These data were used to quantify spatial patterns of exposure, compare hotspot distributions, and assess inequality signals in the Mediterranean region. Original input datasets were derived from publicly available sources, including Aqua MODIS, ERA5-Land, and GRDI.
