WMO Awards recognise outstanding contributions in the field of meteorology, breakthroughs in scientific research, young scientists for their exceptional contributions to meteorology and climatology, and young engineers/scientists working on development hydrometeorology.

Professor Mariolopoulos Award

The WMO Professor Mariolopoulos Award was created in 1996 by the Mariolopoulos-Kanaginis Foundation for the Environmental Sciences, which is in Athens, Greece. The Award is granted every year in recognition of young scientists for exceptional contributions to meteorology and climatology.
