Instruments and techniques are described which were used in a study of dust devils which was made with stationary sensors in the desert of southern New Mexico. Results of observation of 21 storms including measurements of pressure, wind velocity, and other parameters are presented in tabular form. Wind speeds less than 40 knots and pressure decreases of a few millibars were typical. The dust devils were about equally divided between those rotating cyclonically and anticyclonically. A more complete study of dust devils could be made using mobile sensors with more rapid response characteristics, better definition and lower overshoot than those used in this study.
