WIS 2.0 is an information system for the World Meteorological Organization (WMO), designed to collect and disseminate environmental data. Using web architecture and open standards, WIS 2.0 provides simple, timely, and seamless sharing of trusted weather and environmental information. WIS 2.0 is effective and inexpensive, eliminating the challenges that government agencies may have when it comes to sharing Core (publicly available on the Global Cache, no access restrictions) and Recommended (user must access the provider’s WIS 2.0 system, access restrictions may apply) data both publicly and with fellow WMO Member Countries.
