Radar gauges methane release from Arctic lakes

Research by WERC's Katey Walter Anthony and Melanie Engram was featured in UAF News, May 11, 2020:

A University of Alaska Fairbanks-led research team has developed a way to use satellite images to determine the amount of methane being released from northern lakes, a technique that could help climate change modelers better account for this potent greenhouse gas.

By using synthetic aperture radar, or SAR, researchers were able to find a correlation between “brighter” satellite images of frozen lakes and the amount of methane they produce. Comparing those SAR images with ground-level methane measurements confirmed that the satellite readings were consistent with on-site data.
