Recent results from laboratory, field and remote sensing measurements suggest the presence of large methane emissions from the Amazon basin. Here we present regionally integrative, direct trace gas observations from two sites that confirm the presence of large fluxes of methane in eastern Amazônia. Air samples collected on aircraft near Santarém (2.9°S, 55.0°W) and Manaus (2.6°S, 60.0°W) in eastern and central Amazônia show large enhancements of CH4 that are not seen at the NOAA/ESRL background…

CH4 concentrations over the Amazon from GOSAT consistent with in situ vertical profile data

The Amazon Basin contains large wetland ecosystems which are important sources of methane (CH4). Spaceborne observations of atmospheric CH4 can provide constraints on emissions from these remote…

Methane airborne measurements and comparison to global models during BARCA

[1] Tropical regions, especially the Amazon region, account for large emissions of methane (CH_4). Here, we present CH_4 observations from two airborne campaigns conducted within the BARCA (Balanco…

Amazon methane budget derived from multi-year airborne observations highlights regional variations in emissions

Atmospheric methane concentrations were nearly constant between 1999 and 2006, but have been rising since by an average of ~8 ppb per year. Increases in wetland emissions, the largest natural global…

Contribution of regional sources to atmospheric methane over the Amazon Basin in 2010 and 2011

We present an assessment of methane (CH4) atmospheric concentrations over the Amazon Basin for 2010 and 2011 using a 3‐D atmospheric chemical transport model, two wetland emission models, and new…

Determination of the methane budget of the Amazon region utilizing airborne methane observations in combination with atmospheric transport and vegetation modeling

The Amazon basin is an important player in the global methane cycle. Objectives of this work are to establish a forward and inverse modelling framework on regional scale and to determine the methane…

Observational constraints on recent increases in the atmospheric CH4 burden

Measurements of atmospheric CH4 from air samples collected weekly at 46 remote surface sites show that, after a decade of near‐zero growth, globally averaged atmospheric methane increased during 2007…

Seasonality and interannual variability of CH4 fluxes from the eastern Amazon Basin inferred from atmospheric mole fraction profiles

This 13 year record of regularly measured vertical CH4 mole fraction profiles above the eastern Brazilian Amazon shows that CH4 emissions upwind of SAN varied over the years, with highest emissions in 2008, mainly during the wet season, representing 19% of the observed global increase in this year.

Large Methane Emissions From the Pantanal During Rising Water‐Levels Revealed by Regularly Measured Lower Troposphere CH4 Profiles

The Pantanal region of Brazil is the largest seasonally flooded tropical grassland and, according to local chamber measurements, a substantial CH4 source. CH4 emissions from wetlands have recently…

Large and increasing methane emissions from Eastern Amazonia derived from satellite data, 2010–2018

Abstract. We use a global inverse model, satellite data and flask measurements to estimate methane (CH4) emissions from South America, Brazil and the basin of the Amazon River for the period…

Large emissions from floodplain trees close the Amazon methane budget

Close agreement is found between the ‘top-down’ and combined ‘bottom-up’ estimates of large CH4 emissions from trees adapted to permanent or seasonal inundation can account for the emission source that is required to close the Amazon CH4 budget.

Contribution of anthropogenic and natural sources to atmospheric methane variability

The results indicate that wetland emissions dominated the inter-annual variability of methane sources, whereas fire emissions played a smaller role, except during the 1997–1998 El Niño event.
