UTA TRAX and Other Mobile Deployment Status
This page provides diagnostic information on the latest real-time data received from air quality instrumentation packages placed on TRAX light rail cars and other research mobile units across northern Utah. The first table provides the last timestamps of data collected from each deployed device. If a timestamp is shown in green, further information on the sensed measurements are provided in the tables below. If a timestamp is shown in red, data from this device are at least 2 hours old. If a timestamp is shown in purple, data have not been collected for several days or longer. Measurements are highlighted in yellow if a value from an instrument appears to be outside of desired bounds.
