Issue Date: | 2012 | Abstract: | 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). Las entradas de aerosoles procedentes del Continente Africano tienen un importante efecto en el clima y biogeoquímica marina de la Región Canaria. Por tal motivo, se estudiaron los factores que influyen en las concentraciones de partículas en el aire (PTS), la composición química de estas partículas y los flujos de deposición de los metales solubles (Al, Fe, Mn, Co, Ti y Cu).Para ello se tomaron muestras en tres estaciones de la Isla de Gran Canaria (Taliarte al nivel del mar, Tafira at 269 m altitud and Pico de la Gorra 1930 m altitud) desde el 2002. |
