Datasets of air quality, energy, water, carbon and pollutants fluxes/concentrations

Urban communities consume material and energy and eliminate the wastes from the process. Energy and mass are exchanged by urban environments and fluxes are modulated by human activities, such as heating and air conditioning, vehicular traffic, changes in vegetative cover, waste production etc., in what has been termed "urban metabolism". BRIDGE WP3 includes the Data Collection and Analysis activities in BRIDGE case studies, representing a unique attempt to collect and to analyse an integrated database suitable for the development and validation of models and methodologies for the analysis of fluxes between the city and its environment. Task 3.1 - in situ data collection and analysis - applies established and newly developed methodologies aimed at collecting comprehensive data sets by means of in situ observations. Specific objectives are the collection of meteorological data, trace gas emissions, mass, energy, and particle fluxes; assess the role and impact of city vegetation; identify the increase of the energy demand of buildings for cooling purposes; document the sensible heat flux and heat island characteristics of medium and large selected European cities. Task 3.1 is aimed at monitoring the main fluxes, using in-situ observations, in the five BRIDGE case studies of Helsinki, Athens, London, Firenze and Gliwice. These cities were selected as European cities representative of different climates, sizes and socio-economic conditions and will be investigated for the above described drivers and flows. The present document updates Deliverable number 3.1.2. The following paragraphs will provide an overview of ongoing measurement work in the different case studies. Details concerning methods and instrumentation used and expected starting and closing date are provided in Annex. An exhaustive report of methodologies and protocols adopted is to be provided in D.3.4 "BRIDGE observations report" and D.3.5 "BRIDGE observations protocol" due in month 30. The BRIDGE Consortium decided that developing a project database hosting all data collected was unnecessary and hard to realize, due to the heterogeneity of information collected, in terms of time steps, structure of records etc Moreover, it was pointed out that proper data exploitation could not be achieved without direct interaction between data providers on one side and modellers and DSS developers on the other. Data sets were therefore not uploaded on the BRIDGE ftp Server, but will rather be obtained directly by providing institutions, however the location of the data is given in this report.
