BALTAZAR, Sofia. New bioclimatic maps of Lisbon. Spatial modelling of physiological equivalent temperature. Finisterra [online]. 2014, n.98, pp.81-94. ISSN 0430-5027.

Bioclimatic indices provide an evaluation of the effect of climate on thermal sensation and comfort, due to the combined use of various atmospheric parameters. in this context, and bearing in mind the comfort of Lisbon's population, we have developed a methodology for the preparation of bioclimatic maps and performed the spatial modelling of an index applied to the city of Lisbon - the Physiological Equivalent Temperature (PET ). Using Geographic information systems (GIS), we performed spatial modelling of the various meteorological and physical variables of the territory and computed the value of PET for different extreme weather conditions. The resulting maps will contribute to a better knowledge of the thermal comfort in the city of Lisbon and will provide instruments for bioclimatic characterization, spatial planning and civil protection.

Keywords : Bioclimatic maps; urban climate; thermal comfort; Physiological equivalent temperature; Lisbon; Portugal.
