Abstract:Dust storms occur quite frequently in New Mexico. They are the result of when powerful winds pick up large quantities of very dry (and thus, easy to particulate) exposed surface soil and obscures visibility as depicted in Figure NM -1. The low visibility detection system installed along Interstate 10 (I-10) at the southwest corner of New Mexico in what is called the La Playa Region (ancient dry lake bed). This stretch of I-10 is routinely closed due to dust storms, some of which have been fatal in the past. The system was installed at the end of 2011 as part of a technology transfer research project with New Mexico State University acting as the principal investigator.
