How to make a wind-movement recorder from any spare drum-type recorder

Abstract

The automatic recording of wind movement is sometimes essential to experiments in forestry and watershed-management research. Wind-movement data are often obtained by periodic reading of the anemometer dial, but occasionally data are required for variable intervals and at times when observations cannot be made easily. Instruments designed to record wind movement are being manufactured, but they are multiple-stage recorders and are expensive. To our knowledge, no instrument is made for the sole purpose of recording wind movement. So we devised an easy and inexpensive way to convert any drum-type recorder into a wind-movement recorder.
