Roles of the Governing Board• The principal roles of the Governing Board (GB) are to
set policy and to exercise broad oversight of all IGS functions and components. In developing the strategy to achieve the IGS goals in this plan, the Board placed emphasis to:– Balance GB meetings between strategic direction and technical
issues– Improve mechanisms for taking technical and administrative
actions– Continue policy of transparency and openness of GB
discussions and decisions – Ensure diversity of the GB with respect to geographical
distribution and expertise (hydrology, meteorology, climate change, economics, public policy, legal, etc.)
