Abstract: - Whatever study aimed at characterising the “urban heat island”, at determining energy transfers inside urban canyons, at defining comfort indices in an external environment, requires an extended and thorough knowledge of the microclimatic conditions of the concerned urban area. These kinds of studies could be conducted by installing a very large number of measurement stations spread over the whole urban area, but this cannot be proposed for evident reasons of costs linked to the stations themselves and to their management and maintenance. The authors envisaged one possible solution to the problem by integrating the fixed monitoring network with data acquisition units placed aboard of public urban buses. These buses, continually moving on some main arterial streets, would build a virtual network made up of a very large number of measurement stations. The Department of Energetics and Environmental Researches (DREAM) of the University of Palermo has been experimenting with this new technique using original data acquisition equipments installed on moving vehicles with which a large number of tests was done for a long time. In this work the results of a case study carried out by the authors in the years 2003-2004, having as objective the assessment of the time behaviour of some Comfort Indices along an urban canyon in the centre of Palermo city, are reported.
