Methane leak detection,Aliso Canyon. Paired images showing aerial detection (left) and satellite detection (right) of methane plumes (red) from the Aliso Canyon gas leak near Porter Ranch,California,USA. Methane is a potent greenhouse gas. This is the first time such leaks have been observed from space. The images were acquired 11 days apart in January 2016 by NASA's AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) instrument on a NASA ER-2 aircraft at 6.6 kilometres altitude (left) and the Hyperion instrument on NASA's Earth Observing-1 satellite (right). Measurement noise is also present at right | |
