11. Meteorological data: Private good or public good? Public good: Is not used up even if many take part in using it. Not suited for the market Private good: Is used up (shoes!). A requirement for a functioning market. Positive externalities are lost when public goods are commercialised All data (observations and prognosis) owned by MET- Norway are available at zero data price Free license arrangement.hov www.yr.nowww.yr.no, number of unique users per week 2008-2012

Resolution 40 (Cg-XII 1995) WMO policy and practice for the exchange of meteorological and related data and products with guidelines on relationships in commercial meteorological activities http://www.wmo.int/pages/about/Resolution40_en.html As a fundamental principle WMO commits itself to broadening and enhancing the free and unrestricted international exchange of meteorological and related data and products; – (1) Members shall provide on a free and unrestricted basis essential data and products which are necessary for the provision of services in support of the protection of life and property and the well-being of all nations, – (2) Members should also provide the additional data and products which are required to sustain WMO Programmes at the global, regional, and national levels and, further, as agreed, to assist other Members in the provision of meteorological services in their countries. – (3) Members should provide to the research and education communities, for their non-commercial activities, free and unrestricted access to all data and products exchanged under the auspices of WMO

21. GAW links to other WMO initiatives For GFCS – GAW contributes through observations and services related to drivers of climate change (e.g. GHG Bulletin) and applications in various priority areas (e.g. health, agriculture and food security), through the Research and Observations and Monitoring Pillars. For WIGOS and WIS – purpose is to enhance the interoperability and availability of high- quality observational data as the foundation for new and improved services. GAW is actively involved in the implementation of both WIS and WIGOS providing insights into best practices related to atmospheric composition observations and data and also to derive benefits from more sustainable and better integrated observational networks; For WWRP Polar Prediction Project – a multi year research initiative to address the growing requirements for improved weather services on time scales from hours to seasonal in the rapidly changing polar regions. The inclusion of atmospheric composition in the modelling and prediction systems is viewed as a necessity. Improved understanding of processes in polar regions are also expected to have advantages to predictive skills in mid- latitudes.

22. Some words from the last year document Considering the observed and projected changes in polar regions, their importance to the global weather and climate system and the emerging needs for new weather and climate services in polar regions, it should be noted that: GAW is a fundamental programme for building a better understanding of the various feedbacks that occur in polar regions and improving modelling of the weather and climate system; GAW observation activities are coming under increasing threat (especially in polar regions) due to financial pressure exactly at a time when their value is increasing; Models being develop for new environmental services in polar regions require comprehensive atmospheric chemistry and aerosol information at higher special resolution
