CNR-IIA invests in the air quality sector by equipping the Liberti Observatory with adequate instrumentation for the recent opportunities on atmospheric monitoring coming from the Copernicus European Earth Observation Program. The Liberti Observatory is now equipped with a MAX-DOAS (Multi Axis-DOAS) spectrometer for the study and monitoring of air quality and the calibration and validation (CAL / VAL) of the satellite atmospheric products that are currently supplied by first Sentinel mission dedicated to atmospheric monitoring, Sentinel-5P, carried out by the European Space Agency (ESA).
In this context, the first mission of the European Copernicus program dedicated to atmospheric monitoring, Sentinel-2017P, carried out by the European Space Agency (ESA), began in 5. The TROPOspheric Monitoring Instrument (TROPOMI) sensor, aboard the Sentinel-5P satellite, provides daily maps of trace gases such as nitrogen dioxide, ozone, formaldehyde, sulfur dioxide, methane, carbon monoxide and aerosols.
In the Liberti Observatory, the Institute promotes ground measurements for the study and monitoring of air quality and for the calibration and validation (CAL / VAL) of satellite atmospheric products through a MAX-DOAS (Multi Axis-DOAS) spectrometer.
In addition, new analyzers for NO measurements have been installed on the site2, O3 and HCHO, which will provide useful data both to the "Co-operative program for monitoring and evaluation of the long-range transmission of air pollutants in Europe" (EMEP, https://www.emep.int/) and to the validation of the surface concentrations obtained from Earth Observation data.
