Real time air quality observation coverage.

This dataset contains a spatial coverage that records an estimation of the real time concentration of each pollutant at each location of the city of Santiago de Compostela, with a spatial resolution of 4 meters. The following pollutants are estimated: carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO2) and ozone (O3). The estimation is calculated using a spatial interpolation method over the real time observations generated by the network of environmental air quality observation processes of the city of Santiago de Compostela, installed by the TRAFAIR project, funded by the Innovation and Networks Executive Agency (INEA) of the European Commission (EC), through its Connecting Europe Facility (CEF) program.
