                         determining greenhouse gas fluxes at regional scales (104106 km2 
                         ). Here, we describe a new, simple method for estimating the 
                         surface influence of air samples that uses backward trajectories 
                         based on the Lagrangian model Hybrid Single-Particle Lagrangian 
                         Integrated Trajectory Model (HYSPLIT). We determined regions of 
                         influence on a quarterly basis between 2010 and 2018 for four 
                         aircraft vertical profile sites: SAN and ALF in the eastern 
                         Amazon, and RBA and TAB or TEF in the western Amazon. We evaluated 
                         regions of influence in terms of their relative sensitivity to 
                         areas inside and outside the Amazon and their total area inside 
                         the Amazon. Regions of influence varied by quarter and less so by 
                         year. In the first and fourth quarters, the contribution of the 
                         region of influence inside the Amazon was 8393% for all sites, 
                         while in the second and third quarters, it was 5775%. The 
                         interquarter differences are more evident in the eastern than in 
                         the western Amazon. Our analysis indicates that atmospheric 
                         profiles from the western sites are sensitive to 4252.2% of the 
                         Amazon. In contrast, eastern Amazon sites are sensitive to only 
                         10.925.3%. These results may help to spatially resolve the 
                         response of greenhouse gas emissions to climate variability over 
                         Amazon.",
