The main objective of the Action is to develop and make easily
available a physiologically relevant assessment model of the thermal
environment in order to significantly enhance applications related to
health and well-being. The core issues of human biometeorology range from
daily forecasts and warnings of extreme weather, to bioclimate mapping,
urban and regional planning, environmental epidemiology and climate
impacts research. This covers the fields of public weather service, the
public health system, and precautionary planning. The model to be
developed will be based on the-state-of-the-art in the cause-effect
related assessments of the out-door thermal environment.
The Universal Thermal Climate Index UTCI (working title) must meet
the following requirements:
Thermophysiological significance in the whole range of heat exchange
conditions of existing thermal environments Valid in all climates,
seasons, and scales Useful for key applications in human biometeorology
(see section A).
This will be supported through the following specific objectives:
- To identify and make recommendations on the data requirements for
running UTCI in the different applications.
- To develop application oriented parameterisation schemes for the
calculation of mean radiant temperature Tmrt based on different data
bases. - To increase the accessibility of state-of-the-art assessment
procedures and related information using a web portal and other
dissemination platforms. - To produce open and easy guidance and
recommendations for using UTCI within the various applications.
