• Resumen

  • The aerosol optical properties derived from AERONET Cimel CE-318 sunphotometer in El Montsec (42º 3’ N, 0º 43’ E, 1574 m a.s.l.) have been analyzed. The instrument is measuring from 2011 but we have analyzed the quality-assured AERONET level 2.0 data with pre and post field calibration applied (May 2012-April 2013) in the framework of the Red Ibérica de Medida de Aerosoles (RIMA). The photometer has filters centered at 8 wavelengths (340, 380, 440, 500, 675, 870, 940, 1020 nm). Besides the Cimel photometer, the station includes measurements of mass particulate matter, black carbon and particle number concentrations from instruments of the Institute of Environmental Assessment and Water Research (IDAEA-CSIC). This high altitude station is located in a mountain range, distant from anthropogenic aerosol sources, both urban and industrial ones and most of the days out of the boundary layer. Previous studies from in-situ monitoring data have shown the importance of Saharan dust transport and new particle formation (Ripoll et al., 2013).
