While the new device can be operated from the ground, the researchers are now developing a way to use it during large - scale airborne surveys of methane levels. (techtimes.com)
By marking out a surveyed grid (with altitudes) and using a sensitive magnetometer, the natural field was mapped, usually at an area where airborne survey showed a discrete anomaly. (wattsupwiththat.com)
The findings come from a multi-year airborne survey of atmospheric chemistry called HIAPER Pole - to - Pole Observations, or HIPPO. (sciencedaily.com)
