1. LGK Oct 23 Dust emissions The Chilean aerosol-cloud- climate component of VOCALS 2007

2. LGK Oct 23 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?
