4 4 Meeting Name (c) 2006 Challenges facing WMO

5 5 Meeting Name (c) 2006 Challenges for WMO Technical Commissions Basic Commissions  Commission for Basic Systems (CBS)  Commission for Instruments and Methods of Observations (CIMO)  Commission for Hydrology (CHy)  Commission for Atmospheric Sciences (CAS) Applications Commissions  Commission for Aeronautical Meteorology (CAeM)  Commission for Agricultural Meteorology (CAgM)  Joint WMO/IOC technical Commission for Oceanography and Marine Meteorology(JCOMM)  Commission for Climatology (CCl)

6 6 Meeting Name (c) 2006 What is metadata? In this context it is not –the conditions at an observing site although –these can be described by metadata
