                         with large-scale integrating in-situ observations. Considering 
                         that the Amazon Basin represents 50% of the world tropical 
                         rainforest and Methane (CH4) is the second most important 
                         anthropogenic greenhouse gases, contributing with around 18% to 
                         radiative forcing, and in 2014 the CH4 mixing ratio increases of 
                         9ppb in comparison with the previous year, reaching 1833ppb, is 
                         important understand the behavior of the Amazon Basin in relation 
                         to this greenhouse gas. Then, observing the global importance of 
                         CH4 and uncertainties in the emission of this greenhouse gases in 
                         the Amazon Basin, this study aimed to determine CH4 emission in 
                         the Amazon Basin. Were used regular vertical profiles in 4 sites 
                         distributed over the basin from east to west, Alta Floresta (ALF; 
                         8.80ºS, 56.75ºW), Rio Branco (RBA; 9.38ºS, 67.62ºW), Santar{\'e}m 
                         (SAN; 2.86ºS; 54.95ºW) and Tabatinga (TAB; 5.96ºS, 70.06ºW). Since 
                         2010 samples are collected, fortnightly, aboard light aircraft 
                         between 300m and 4.4km. From the flux estimates we calculated 
                         basin wide budgets with some differentiation of underlying 
                         processes based on carbon monoxide from fires. The results showed 
                         that the Amazon Basin was a source of CH4 during the study period, 
                         but the CH4 emission variable in the different regions and 
                         variability with the years, these can be related with the 
                         climatological variations, 2010 and 2012 were driers years and 
                         2011 and 2013 were wet years. With these results is possible to 
                         observe the importance of conducting studies on a regional scale 
                         to elucidate the behavior of the entire Amazon Basin. And the 
                         importance of long-term studies due the variation in emissions 
                         year by year, so that the results can be assumed to average 
                         behavior a long time series is necessary to take into account the 
                         methane balance from the Amazon Basin.",
