Abstract
The design and construction of a small, highly responsive pressure instrument with a sensitivity of approximately 0.1 mb is discussed. Two pressure sensors, or microbarophones, were used on a mobile tower to measure pressure variations near and within several dust devils. A pressure trace of a dust devil penetration is presented. The microtbarophone is considered to have sufficient merit that it may be of use in other applications involving micro-pressure measurements.
