• Resumen

  • [EN]African dust pulses have important effects on the climate and marine biogeochemistry of the Canary Region. Common factors influencing the air mass concentration, elemental and composition of aerosol particles and atmospheric deposition fluxes of soluble Fe, Al, Mn, Ti, Cu and Co were examined. Aerosol samples have been collected at three stations in Gran Canaria Island (Taliarte at sea level, Tafira at 269 m altitude and Pico de la Gorra 1930 m altitude) since 2002. Air-mass back trajectories (HySPLIT, NOAA) suggested that the Sahara desert is the major sources of dust (dominant during 32-50% of days) while the Sahel desert was the major source only 2-10% of the time (maximum in summerautumn).
