Board of Directors
In June 2019, the World Meteorological Congress approved a reform of the WMO governance and a vision for 2030 as well as other changes that called for an overhaul of the structure of the Secretariat. One of the most important changes implemented thus far is the creation of a Board of Directors. The Board, composed of senior Directors, meets once a month to discuss overall progress towards achieving departmental targets and overall organizational objectives and goals. The senior management team of Directors signs annual compacts (accountability documents) to ensure delivery on the Organization's high-level objectives.
