Weather and climate observations provide critical information that supports both the research and operational communities. Traditionally, the Federal Government has acted as the primary source for weather and climate data; however, over the past few decades, private sector companies have increasingly played a role in the production and dissemination of these data. The current economic landscape has resulted in an increased focus on more effective, targeted use of available Federal resources. As a result, the Federal Government is under pressure to closely examine and optimize its investment in weather- and climate-related activities, including those associated with development, deployment and operation of observing networks. This may manifest itself in an evolving paradigm where there is more reliance on the private sector for weather and climate data and information. This session will build on previous sessions that have examined the topic of the commercialization of weather and climate data, with a focus on the following: the expansion of commercial data providers, the future role of the government in the deployment and operation of observing systems, and challenges associated with the commercialization of weather and climate data.
