      note          = "Abstract: Urban air quality challenges represent the
                       second environmental priority of the European Commission
                       because of its effects on human health. With this premise,
                       this work developed in the context of the research project
                       TRAFAIR: Understanding traffic flows to improve air quality
                       (2017-EU-IA-0167) has focused on the processing and
                       publication of air quality monitoring data sets in the
                       prototype of the infrastructure deployed by the project for
                       the city of Zaragoza.  Firstly, the sensor networks of the
                       monitoring systems for data collection have been
                       identified: the regulated stations of the Zaragoza City
                       Council and the low-cost sensors deployed by the TRAFAIR
                       project. Based on the data provided by the sensors, a
                       database model has been implemented for their storage.
                       Secondly, an architecture has been proposed for publishing
                       part of the data stored in the TRAFAIR database through the
                       Geoserver spatial data server. For this purpose, both
                       discrete phenomenon layers, partial views of the
                       information stored in the database, and spatial coverage
                       generated from interpolation algorithms have been modeled.
                       As for open access publishing, a software has been
                       implemented and adapted for the creation of the layers
                       through the Geoserver Rest API, which in turn has allowed
                       access to the data through standard services defined by the
                       Open Geospatial Consortium (OGC). For the dissemination of
                       the data in open data portals, we have also participated in
                       the implementation of a software to export the information
                       of the Geoserver layers as GeoDCAT-AP type metadata in CKAN
                       type servers.  In addition, a strategy has been proposed to
                       distribute some data sets in specific formats (CSV, RDF,
                       NetCDF). Finally, the quality of the published spatial data
                       has been analyzed from different points of view: conformity
                       with the INSPIRE data specifications, quality of the
                       GeoDCAT-AP metadata from a methodology based on the
                       procedure used by the European Data Portal; analysis of the
                       completeness of the observations; and analysis of the
                       accuracy of the observations from the TRAFAIR project
                       sensors.",
