Daily fluxes of CH₄ determined from the measurements using box models and inverse modeling were between 168 (± 50) and 456 (± 145) mg CH₄⋅m^-2⋅d^-1 for the areas overflown, very high compared with those of previous Amazon basin studies. If the seasonality of the CH₄ emissions is comparable to other parts of the Amazon Basin, the region could contribute as much as 8% of annual Amazonian CH₄ emissions.enAmazonianWetlandAmazon rainforestSeasonalityMethaneEnvironmental scienceMethane emissionsAtmospheric sciencesSampling (signal processing)Dry seasonarticle
