Introduction: Thermal stress risk management requires the development of applied indicators. The purpose of this study was to evaluate the performance of the two indicators including WBGT and TWL and their fit with the tympanic temperature. Method: This cross-sectional study was carried out on 101 urban service personnel in a heat and dry area in 2016. The measurements of the study indices inc...

Existing methods for estimating heat stress, enshrined in British/International Standards (the Wet Bulb Globe Temperature (WBGT) index [BS EN 27243] and the Required Sweat Rate equation [BS EN 12515; ISO 7933 modi®ed]), assume that the clothing worn by the individual is water vapour permeable; the WBGT index also assumes that the clothing is relatively light. Because most forms of personal prot...

Abstract. Climate models' outputs are affected by biases that need to be detected and adjusted model climate impacts. Many hazards climate-related impacts associated with the interaction between multiple drivers, i.e. compound events. So far typically assessed based on hazard of interest, it is unclear how much a potential bias in dependence drivers contributes overall interact. Here, copula th...
