Satellites Size Up Bubbles of Methane in Lake Ice

Synthetic Aperture Radar is offering scientists a new way to measure how much of the potent greenhouse gas is bubbling up from frozen Arctic lakes.

NASA Earth Observatory images by Lauren Dauphin, using data from Engram, Melanie, et al. (2020) and Landsat data from the U.S. Geological Survey. The researchers used data collected by the Phased Array type L-band Synthetic Aperture Radar (PALSAR) sensor on the Japanese Advanced Land Observing Satellite (ALOS). The data is processed and stored by the Alaska Satellite Facility at the University of Alaska Fairbanks. Story by Adam Voiland.
