Bioclimatically negative effects as heat islands, big temperature excursions between day and night, inversion weather situations and reduced dispersion of emissions are problems present in all metropolitan areas.
Therefore it is of great importance to know not only the emission sources and pollution values (all cities have an air quality monitoring network), but also the macro- and microclimatic values conditioning the climatic evolutions in different, typical climatic situations (i.e. see also the contribution on traffic for Rome, where thanks to the implementation of the A.T.M.O.S.FE.R.A system with climatic data as temperature, rainfall and wind presence and speed a synthetic index for the whole city has been elaborated which permits precise air pollution forecasting). But the collection and elaboration of this kind of data is mainly for controlling and to decide emergency measures and not for urban planning purposes.
Basic climatic data as temperature, humidity, solar radiation etc. are available in each city, even for long term periods and several stations, so that they can be easily related to the territory, passing from point data to spatial data, and therefor expressed in maps such as Berlin, Milan and Moscow have done. And it is mainly with these basic climatic maps that planning indications can be deduced and other maps be elaborated which provide precise indications for the urban planning in order to reduce the negative effects of the human impact on microclimatic level
