Abstract

As part of the work plan (2009-2011) of the Group on Earth Observations (GEO), the Task 09-02d"Global Monitoring Plan for Atmospheric Mercury"was established in supporting the achievement of the goals of GEOSS and other on-going international programs (e.g. GAW, UNEP Mercury Program) and conventions(i.e.UNECE-LRTAP TF HTAP) aiming to establish a global observation system for mercury.The overall goal of the GMOS project was to develop a coordinated global observation system for mercury,including ground-based stations,ad-hoc oceanographic cruises over the Pacific,the Atlantic and the Mediterranean, and free tropospheric mercury measurements. This network, consisting in more than 40 monitoring sites globally distributed at high altitude and sea level locations in the northern and southern hemispheres, including polar areas, are providing high quality data for the validation and application of regional and global scale atmospheric models,to give a firm basis for future policy development and implementation.The CNR-IIA monitoring station "Monte Curcio" is a GMOS site as well as is a Regional GAW site in the framework of the regional infrastructure in the Meidterranean area.

Goals

a) To expand a Global Observation System for Mercury able to provide ambient concentrations and deposition fluxes of mercury species around the world, by combining observations from permanent ground-based stations, and from oceanographic and tropospheric measurement campaigns;
b) to convey GMOS network to GOS4M to increase the availability and quality of in situ Hg information thus contributing to the Earth Observation data in the environment;
c) To validate regional and global scale atmospheric mercury modelling systems able to predict the temporal variations and spatial distributions of ambient concentrations of mercury, and Hg fluxes to and from terrestrial and aquatic receptors;
d) To develop interoperable tools to allow the sharing of observational and models output data produced by GMOS, as well as produced within regional network for the purposes of research and policy development and implementation;
e) Measurements of other key atmospheric constituents at the global monitoring sites are necessary to develop a better understanding of the global redistribution of Hg, and to further refine the parameterisation of key processes in global and regional atmospheric mercury models.
