Close relationships between GISCs allow easier Close relationships between GISCs allow easier exchange of meteorological data, with a goal of exchange of meteorological data, with a goal of enhancing National and Regional NWP programs.enhancing National and Regional NWP programs.

WIS will reshape the look, feel and core of the WMO community over the next 10-15 years.

By allowing non-traditional and emerging economy nations to become core players in the WMO community to obtain data for NWP purposes at a low cost

By modernizing the technology WMO is using and reducing the use of Met-specific technology

By increasing flexibility of data formats and the use of existing and future open standard formats

BY laying the framework to have strict controls over the end use of meteorological data yet still provide for wide dissemination
