Two decades (2004-2023) of global seasonal wetland methane emissions at 1 km spatial resolution inferred from Landsat inundation data
AGU 2024
atmospheric sciences | 13 december 2024
Zichong Chen, Haipeng Lin, Nicholas Balasus, A. An...
Natural wetlands are the largest source of atmospheric methane, contributing 20-40% of global methane emissions. Wetland emissions are thought to have...
