             abstract = "The spatiotemporal variability of the greenhouse gas methane (CH4) 
                         in the atmosphere over the Amazon is studied using data from the 
                         space-borne measurements of the Atmospheric Infrared Sounder on 
                         board NASAs AQUA satellite for the period 200312. The results show 
                         a pronounced variability of this gas over the Amazon Basin 
                         lowlands region, where wetland areas occur. CH4 has a well-defined 
                         seasonal behavior, with a progressive increase of its 
                         concentration during the dry season, followed by a decrease during 
                         the wet season. Concerning this variability, the present study 
                         indicates the important role of ENSO in modulating the variability 
                         of CH4 emissions over the northern Amazon, where this association 
                         seems to be mostly linked to changes in flooded areas in response 
                         to ENSO-related precipitation changes. In this region, a CH4 
                         decrease (increase) is due to the El Nino-related (La 
                         Nina-related) dryness (wetness). On the other hand, an increase 
                         (decrease) in the biomass burning over the southeastern Amazon 
                         during very dry (wet) years explains the increase (decrease) in 
                         CH4 emissions in this region. The present analysis identifies the 
                         two main areas of the Amazon, its northern and southeastern 
                         sectors, with remarkable interannual variations of CH4. This 
                         result might be useful for future monitoring of the variations in 
                         the concentration of CH4, the second-most important greenhouse 
                         gas, in this area.",
