Located within the grounds of the CID CSIC in Barcelona
(41° 23’14.28″N, 2°6’56.34″E, 77 meters amsl).

Previously, this site was installed at a nearby location, but was moved to its current location in January 2011, where it will remain.


Research carried out at this site is included in the Air Quality and Exposure assessment research lines.

This research aims to:

  • Interpret the variability of levels, composition and physical properties of atmospheric aerosols at an urban location in the Western Mediterranean

  • Identify the source origin and atmospheric processes controlling aerosol levels and characteristics

  • To quantify the origin of PM components with special interest in organic aerosols and the urban contribution to mineral matter.

  • To support air quality action plans.

  • To provide a long-term time series of regulated and novel metrics as a relevant input to epidemiological and health impact assessment (HIA) studies performed within this research team and in collaboration with internationally recognised research centres.

  • To investigate the linkages between PM sources and health outcomes


PMx levels and PM speciation measurements obtained in the framework of the national research projects are available since 2002
