WIGOS An important aspect of WIGOS (WMO Integrated Global Observing System) implementation is ensuring maximum usefulness of WIGOS observations. Observations without metadata are of very limited use: it is only when accompanied by adequate metadata (data describing the data) that the full potential of the observations can be utilized. Two complementary types of metadata are required: discovery metadata and interpretation/ description or observational metadata. Discovery metadata facilitate data discovery, access and retrieval. They are WIS metadata and are specified and handled as part of WIS. Interpretation/description or observational metadata enable data values to be interpreted in context. They constitute WIGOS metadata and are the subject of this WIGOS standard for the interpretation metadata required for the effective utilization of observations from all WIGOS component observing systems by all users. The WMO Integrated Global Observing System metadata should describe the observed variable, the conditions under which it was observed, how it was measured, and how the data have been processed, in order to provide users with confidence that the data are appropriate for their application. The Global Climate Observing System(GCOS) Climate Monitoring Principle 2.2.1(c) (see Appendix 2.2) describes the relevance of metadata as
