The principal purpose of the program is to enable users of meteorological services to select consultants with greater confidence in the quality and reliability of the products and services they will receive. CCMs must demonstrate exemplary qualities of character and devotion to high professional standards. CCMs are highly regarded by their peers in meteorology. They are considered experts in the application of weather information to a host of practical challenges ranging from specialized forecasts to engineering design support and expert testimony on weather-related court cases.
