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.",
