S P A R C 2010 Newsletter n o 36 January STRATOSPHERIC PROCESSES AND THEIR ROLE IN CLIMATE A Project of the World Climate Research Programme I C Report on 2010 SOLARIS Activities and Future Plans K. Matthes, Deutsches GeoForschungsZentrum Potsdam, and Freie Universitä, Germany (matthes@gfz-potsdam.de) K. Kodera, Nagoya University, Japan (kodera@stelab.nagoya-u.ac.jp) This report is aimed at describing SOLARIS activities in 2010, as well as outlining future plans. It is structured as follows: First, a summary of the SOLARIS workshop and the SCOSTEP side-meeting in 2010 will be given; second, open ques- tions that arose from those meetings will be discussed; and third, future studies will be presented. All SOLARIS activities and future plans are also available on the newly designed and regularly updated website: http://sparcsolaris.gfz-potsdam.de/. Summary of the Second SOLARIS Workshop and SCOSTEP Side-meeting in 2010 The second SOLARIS (SOLAR Inluence for SPARC) workshop was held from 10- 12 March 2010 and was hosted by the Ger- man Center for Geosciences in Potsdam, Germany. Approximately 38 participants from 8 countries participated in the two- and-a-half day meeting to review the latest results in the ield of modelling the solar inluence on climate, and to decide about future coordinated SOLARIS modelling activities. Additionally, a SOLARIS side meeting was held during the SCOSTEP conference in July 2010 in Berlin, Germa- ny, with 23 participants, some of who had been unable to attend the spring meeting at GFZ Potsdam.
