A team of researchers at the University of Michigan found that tracking windshield wiper activity can provide faster, more accurate rainfall data than radar and rain gauge systems currently in use. The researchers used a fleet of 70 cars and tracked when wipers were being used and matched it with video from onboard cameras to document rainfall and found that tracking windshield wiper activity can provide faster, more accurate rainfall data.
The best warnings for flood conditions come from radar tracking from satellites and geographically dispersed rain gauges attached to buildings and other structures, but our current system for collecting rainfall data has some limitations. Both these data sources lack the ability to know what is happening at the street-level.
Vasudevan added, “If you have fine-grain predictions of where flooding occurs, you can control water networks efficiently and effectively to prevent all sorts of dangerous chemicals from appearing inside our water supply due to runoff.”
Creating a blanket system of sensors across a city for street-level data on rain events would be costly but by using cars already on the road, we could save infrastructure costs by tapping a resource already in place now that will only grow larger in the future.
Why This Matters: We know that rainstorms are getting stronger and wetter, and that flash floods and sewer overflows are major issues as a result. The research shows the value for weather and climate that more and better data can provide — it represents a promising first step in creating a smart infrastructure system that is fed by and responds to data as it is collected from vehicles on the road. The University points out in its announcement that communities armed with real-time data could move more quickly to prevent flash-flooding or sewage overflows, which represent a rising threat to property, infrastructure and the environment. When added to other technological advancements like “smart” stormwater systems—infrastructure outfitted with autonomous sensors and valves—municipalities could potentially take in data from connected vehicles to predict and prevent flooding. Revolutionary! Just like the windshield wiper!
This week, just in time for Thanksgiving, we talk with Adam Kolton, the Executive Director of the Alaska Wilderness League about the Arctic National Wildlife Refuge, Arctic Indigenous Communities, and conserving Alaskan wilderness. Watch the entire interview. Here are a few highlights: On the Arctic National Wildlife Refuge: “This is the area where hundreds of […]
This week we had the pleasure of sitting with Luhut Binsar Pandjaitan, Indonesia’s Coordinating Minister for Maritime Affairs and Investment, a title he’s held since October 2019. We asked the minister about how Indonesia is balancing the precarious equation of conserving its rich biodiversity while addressing the duel climate and COVID crises. Now that […]
Sure he may perennially be one of People Magazine’s sexiest men alive (well Michael B. Jordon won this year), but now HGTV’s Jonathan Scott is on a real “Power Trip.” On Monday he premiered on PBS a new documentary he wrote and directed about how solar energy development is being stifled by what he calls […]
