Das Projekt "Thermische Behaglichkeit und staedtisches Klima in tropischen Gebieten" wird vom Umweltbundesamt gefördert und von Universität Kassel, Fachbereich 13 Stadtplanung,Landschaftsplanung, Fachgebiet Lufthygiene,Stadtklima durchgeführt. In tropical costal climates of Brasil urban climate investigations were carried out. This includes meteorological measurements. This data could be used to calculate thermal comfort on the base of the physiological equivalent temperature (PET) and the standard equivalent temperature (SET). The investigation should give a thermal pattern of brasilian cities along the costal line. The investigated cites are Salvador/Bahia, Joao Pessoa, Rio Claro and Belo Horizonte.
