Analysis of the observations of temperature carried out at the meteorological station of the institute of physics

In the urban area of Turin, meteorological observations were recorded since more than a century, but in different places, and there is not a place in which data were available for the entire period (Di Napoli and Mercalli, 2008). The institute of Physics of the University was equipped with a meteorological station for some years between the two World Wars, but then this observing point was dismissed. Subsequently, in the 1991, the geophysics group of the Institute of physics decided to start regular observations on the roof of the neighbor buillding edificated nearby the old building (Bonino et al., 1998). These observations are continuing nowadays, coordinated by the Atmospheric Physics and Meteorology group of the Department of Physics, and their database - even if some period of missing data are present - is close to celebrate its first 30-years period of observations. The station is constantly maintained by a dedicated staff of technicians and instruments were regularly calibrated. In occasion of the anniversary, the group has decided to analyze the series of data, starting from the temperature. Instantaneous raw data were then accurately managed and checked, and then daily, monthly and annual averages were calculated, as well as more refined statistical methods were applied to the data. Since the institute of physics is located not far from the central area of Turin, the behavior of the data gathered at this station could be considered as representative of the urban area of Turin. During this presentation, after a short description of the station and the instruments used, we would like to show the results of the analyses carried out on these data, with an eye to the climatological behavior.
