Assess the need for the development of new model and measurement products for improving our understanding of the impacts of the atmospheric deposition of nitrogen species and dust (iron) to the ocean
Review the present information on the atmospheric deposition of phosphorus species to both the marine and terrestrial environments, considering both natural and anthropogenic sources, and evaluate the impact of atmospheric phosphorus deposition on marine and terrestrial ecosystems.Consider whether such a review of any other substance would be useful
Work with the WMO Sand and Dust Storm Warning and Assessment System, and with the WMO Precipitation Chemistry Data Synthesis and Community Project to evaluate the needs of the marine community, and assist in clearly articulating them in the development of these WMO efforts
