Knowledge of the absolute wind velocity near the surface of the ocean is a requirement of the World Ocean Circulation
Experiment (WOCE) and other large programs directed towards understanding air-sea interactions and how ocean circulation and
climate are interrelated. The measurement is made possible using IMET (Improved METeorology) modules, a next generation
meteorological data acquisition system developed as part of the WOCE program. An IMET system consists of a set of intelligent
modules for each measurement variable, with data being recorded on a computer, typically PC-based. The IMET wind module
includes a propeller for wind speed, a vane and optical encoder for wind direction, a flux gate compass for the north reference, and
microprocessor-based electronics for control and data formatting. The IMET Global Positioning System (GPS) module includes a
five chanel GPS receiver and microprocessor based electronics for control and data formatting. These modules, as part of the
complete measurement suite, result in a self-contained system that can make accurate measurements from research ships, drifting
and moored buoys, and volunteer observing ships (VOS).
