Abstract
Methane (CH<sub>4</sub>) mole fractions from the large semiseasonal Llanos de Moxos wetlands (∼70,000 km<sup>2</sup>) in northern Bolivia were measured by aircraft flights and ground sampling during early March 2019 (late wet season). Daily fluxes of CH<sub>4</sub> determined from the measurements using box models and inverse modeling were between 168 (± 50) and 456 (± 145) mg CH<sub>4</sub>⋅m<sup>-2</sup>⋅d<sup>-1</sup> for the areas overflown, very high compared with those of previous Amazon basin studies. If the seasonality of the CH<sub>4</sub> emissions is comparable to other parts of the Amazon Basin, the region could contribute as much as 8% of annual Amazonian CH<sub>4</sub> emissions.
