The Met One 024A wind direction sensor provides azimuth data for use in micrometeorological measurements related to operational studies and research. This sensor is especially useful when a low starting threshold, a high damping ratio or a short delay distance is required. For example, in making Paquill determinations or for use with sigma computers, both a high damping ratio and a short delay distance are mandatory performance criteria.

The 024A is presently employed in continuous service in environments ranging from Antarctic cold to arid desert regions.
