The questions• Which are the emission
strengths and distributions of natural and anthropogenic emissions of aerosols and precursors over the area? (Emphasis on sulfur and dust)
• Which is the regional distribution of these aerosols? Which is the relative contribution of anthropogenic and natural sources ?
• How (much) do the anthropogenic sulfate aerosols affect cloud properties off the coast from Chile?
