Italy’s leading national research institution, the CNR has been supporting research activity at Ny-Ålesund since 1997, when the scientific station “Dirigibile Italia” was acquired. This infrastructure supports Arctic research conducted by the national research community. In 2008, it was improved through the construction of the Amundsen-Nobile Climate Change Tower and the actikvity largely enlarged with the Climate Change Tower Integrated Project (CCT-IP - www.isac.cnr.it/~radiclim/CCTower). Scientific cooperation, particularly focused on atmospheric science including pollutants distribution and ozone studies, on oceanography and on marine biology and biodiversity was developed by CNR scientists in particular with NPI and AWI; CNR is coordinating actions (EU-GMOS project) to improve and implement the observational system related to mercury. CNR is also involved in the SIOS preparatory phase project, and in Italy it is engaged to coordinate interested Italian expertises in a common scientific plan and actively promote Italian participation to SIOS final multidisciplinary platform. In the years to come, CNR intends to promote the improvement of research activity and to reinforce international cooperation of the Italian research groups, and to provide a significant contribution to the observational system in the Arctic, following the lines recommended by SAON. Together with the improvement/development of a supersite at Ny-Ålesund and large contribution to SIOS, CNR will operate to contribute/sustain thematic networks (Polar-AOD for aerosol and GMOS for mercury leading from CNR).
