Field validation was conducted using calibrated reflectance tarps, and spectrally resampled NIS data served as a reference standard.

Methane is a potent greenhouse gas, second to carbon dioxide in its overall influence on anthropogenic warming at Earth’s surface, so scientists are keen to keep a close eye on emissions of the gas, both natural and anthropogenic. Thorough records of methane emissions from the landscape allow researchers to better understand processes that contribute emissions, forecast changes in ecosystems, validate models of land–atmosphere exchanges, and estimate regional and continental methane budgets.
