Nox Trends in Valladolid city
<p>This indicator is included in the list of indicators for Challenge 5. Air Quality. See table below with the total set of KPIs related to Air Quality (AQ) Challenge.</p> <p>Other indicators are defined to assess a general impact of a NBS on AQ at building, district or city scale. However, this indicator is focused on the impact of specific NBS on a polluted gaseous stream before being released into the urban atmosphere.</p> <p>This indicator has been mainly defined for Urban Garden BioFilter but in future can be used for other NBS to be installed in outdoor pipes to capture pollutants. At lab scale, the impact of this NBS has been measured by a setup with air characterization upstream and downstream of the filter. However at real scale measurements of AQ are more complicated. The system is going to be installed in the underground car park “Plaza Zorrilla”. Inlet air can be measured by installing a sensor in the area where air is going to be extracted or inside of the inlet pipe. However, outlet air cannot be capture directly, it is a very high surface to cover. Thus, it is going to be installed two measure points before and after the implementation of the BioFilter. One of them next to the outdoor area and the other one far away but in the Zorrilla Sq. too. These three measure point will count with PM, NOX and O3 sensors.</p>
