Abstract: We measured the composition of the aerosols linked to transatlantic transport from North America to Izaña Observatory, Tenerife. The eastward-moving depressions prompt aerosols export. The seasonal shift of the westerlies stream over the aerosol sources prompts seasonality in the aerosol composition. High loads of dust, organics and sulfate occur in spring and elemental carbon occurs in summer. Aerosol population in the westerly winds over the North Atlantic is dominated by dust and organics.
