Navy oceanographic meteorological automatic device

The Navy oceanographic meteorological automatic device (NOMAD) is an anchored automated weather station developed shortly after World War II and still used today.

The NOMAD has a boat-shaped hull made from aluminum, and it provides relatively high cost-effectiveness and excellent long-term survivability in severe weather.

[2] In July 1946, the United States Navy's Bureau of Ships became involved in a program to develop automatic weather station buoys.

To support such a mooring, a similarly shaped hull had to be 20 feet (6.1 m) long and displace approximately 20,000 pounds (9,072 kg).

It was also the first anchored automated station to detect the formation of a hurricane and alert weather observers on land.
