Objective
To obtain a parametric description of the transformation and removal of nitrogen compounds in the marine atmosphere, involving aerosols and clouds.
The project is based on results from project STEP-CT90-0047 on the production of sea salt aerosol and the dispersal of aerosol throughout the marine boundary layer, the transformation of nitrogen compounds due to the interaction between sea salt aerosol and nitrogen compounds and the scavenging of nitrogen aerosols in clouds, and the deposition of aerosols on water surfaces. The expected achievement of this extension is the application of the 2-D cloud model to much less soluble compounds (e.g. NOX), and the use of the model to assess the up-going fluxes of the insoluble species as well as soluble species attached to aerosols, with the goal to provide a parameterization for larger scale models.
The vertical fluxes of nitrogen oxides not only enable them to participate in the long range transport but also affect the O3 concentration and transport properties. Thus, the knowledge of these vertical fluxes is important for larger scale models. Other expected achievements are the improvement of both the sea salt source functions and the over-water deposition rates based on new experimental data and improved meteorological descriptions of the marine boundary layer, and the integration of the various results.
Available European and global models will be used in the study.
