Air quality in Navarre

[Air quality assessment](https://www.miteco.gob.es/images/es/Cap3_Criterios%20evaluacion_tcm30-186479.pdf) is defined as the result of any method for measuring, calculating, predicting or estimating the concentrations of a pollutant in ambient air or its surface deposit at a given time. In Navarre it is carried out by means of [measurements](https://www.miteco.gob.es/es/calidad-y-evaluacion-ambiental/temas/atmosfera-y-calidad-del-aire/calidad-del-aire/evaluacion-datos/redes/default.aspx) in a series of sampling points that are considered representative of each of the areas in which the territory has been divided and that make up the Navarre Air Quality Monitoring Network. This Network has analysers and sensors that measure the pollutants set by the air quality regulations, mainly sulphur dioxide (SO2), nitrogen oxides (NO and NO2), tropospheric ozone, carbon monoxide (CO), benzene and suspended particles (PM10 and PM2.5). In addition, meteorological parameters such as wind speed and direction, temperature, relative humidity, pressure, radiation and precipitation are measured. In this sheet you can download the *validated time data of the current year*, which are updated periodically. *Unvalidated time data of the last 60 days*, updated with time frequency, can be downloaded in the [Air Quality in Navarre, last 60 days](/en/dataset/quality-of-air-in-navarra-ltimos-60-d-as) tab. The structure of the files and interpretation of the data is included in the [explanatory document](https://gobiernoabierto.navarra.es/sites/default/files/opendata/manual_calidad_del_aire.pdf).
