Global Extreme Heat Hazard

Published by the World Bank (2017), this is a global data layer for extreme heat hazard, which is classified based on an existing and widely accepted heat stress indicator, the Wet Bulb Globe Temperature (WBGT, in °C) – more specifically the daily maximum WGBT. The WBGT has an obvious relevance for human health, but it is relevant in all kinds of projects and sectors, including infrastructure related, as heat stress affects personnel and stakeholders, and therefore the design of buildings and infrastructure. Heat stress studies in the scientific literature that make use of the WBGT apply thresholds of 28°C and 32°C to categorise heat stress risk. The damaging intensity thresholds are applied following this definition of slight/low (<28°C), moderate/high (28-32°C) and severe/very high (>32°C) heat stress.

Extra Info: There are three global GeoTIFF files in total, which can be combined into one single collection 5 year, 20 year and 100 year return period.
