AB: The Canary Islands are an archipelago of volcanic origin located off the west coast of Africa. Sahara dust storms continuously inject dust particles into the atmospheric boundary layer and lower troposphere of these islands. While these dust events occur during the whole year; they have major significance in terms of aerosol distribution over the Canary Islands primarily throughout the period between January and April. In March 2003 we measured aerosol size and mass distributions, and aerosol optical thickness in two of the seven islands. We performed measurements in Telde of Gran Canaria and at El Teide on Tenerife. The latter is a dormant volcano with a height of 3,718 meters. The Teide is the highest elevation in all the Atlantic Ocean. Its peak is well above the Saharan Air Layer and provides the scenario for unperturbed clean air mass measurements even during dust events. In this presentation we compare aerosol size and mass distributions, and aerosol optical thickness for these two locations.
