Making the invisible visible

07/22/19 Berkeley Lab — Berkeley researchers have developed a new type of sensor network that is affordable and capable of tracking soot (black carbon). With more than 100 custom-built sensors installed across West Oakland for 100 days, the team created the largest black carbon monitoring network deployed in a single city.
