As part of special projects, the Air Quality Monitoring Network (RSQA) measures the concentrations of pollutants at the nomadic station. Its objective is to deepen our knowledge of ambient air quality. As its name indicates, this station will change location at the end of each measurement campaign, which may last from 12 to 24 months. The Nomad station continuously measures: ozone (O3), fine particles (PM2.5), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), elemental carbon (CE) and ultrafine particles (PUF); as well as spot measurements of breathable particles (PM10) and total suspended particles (PST) with metal analysis on the latter.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
