We document observations of dust devil vortices using a linear array of 10 miniature pressure- and sunlight-logging stations in summer 2013 at La Jornada Experimental Range in the southwestern USA. These data provide a census of vortex and dust-devil activity at this site. The simultaneous spatially-distributed measurements resolve the horizontal pressure structure of several dust devil encounters, and the data can be fit well with an analytic model, giving independent measures of vortex size and intensity. © 2015 Elsevier B.V.
