During a very hot day last summer, more than 100 people drove along pre-planned routes in the Truckee Meadows region, collecting thousands of data points measuring temperature and humidity at specific, coordinated intervals. Equipped with sensors and bumper magnets that gathered measurements every second, the volunteers helped researchers obtain data that was later used to create models of urban heat across the region throughout the day. Five months later, researchers from the Reno-Sparks Heat Mapping Project have shared the resulting data and modeled temperature maps that help illustrate how heat varies across the city at different times. This initiative was led by the Nevada State Climate Office at University of Nevada Reno (UNR), with support from scientists at the Desert Research Institute (DRI) and volunteers from more local and Tribal governmental organizations and community groups. The detailed results would not have been possible without the help of community volunteers and the on-the-ground measurements they provided from the 200-square-mile study area. “This information will allow us to achieve our ultimate goals—better decision-making, creating safer communities, and protecting our neighbors,” said Thomas Albright of UNR.
