Significant requirements in wind-instrumentation or -measurement techniques are briefly reviewed with respect to the operational or research function in which they are employed. It is concluded that sensing devices can be obtained or have been devised which are, in principle, satisfactory for the field investigation of most practical and many theoretical problems arising in air-pollution studies. However, devices for rapid output-data reduction, transformation, or manipulation in a form to be of greatest utility are badly needed, preferably as integral parts of the wind-instrumentation setup itself. Progress in developments in this direction is reported and future needs pointed out.
