| Abstract | Carbon Monoxide (CO) is emitted to the atmosphere over the Amazon by biomass combustion as well as being formed by oxidation of hydrocarbons. Carbon dioxide (CO2) is emitted by combustion and respiration and absorbed by photosynthesis. CO and CO2 mixing ratios were measured continuously at Maxaranguape, a coastal site, and Tapajos km67, an inland site, during the BARCA (Balanço Atmosférico Regional de Carbono na Amazônia) campaign. We report here results from November 2008 through May 2009 including both the two intensive flight campaigns, BARCA-A in November-December 2008 and BARCA-B in May 2009 and the period between. The Maxaranguape coastal station is located on a bluff overlooking the Atlantic Ocean about 40 km north of Natal. Steady easterly trade winds deliver tropical marine air to the site most of the time except for occasional periods of nighttime land breezes. The Tapajos km67 site is located in the Tapajos National Forest about 60 km south of Santarem. Trajectory analysis indicates that coastal air off northeast Brazil contributes to the easterly flow entering the Amazon basin. Mixing ratio gradients between this pair of sites is an overall indicator of the net influence of sources in the eastern Amazon basin. During the dry season CO concentrations at km67 exceed the mixing ration in marine air by 100 - 200 ppb, indicating the influence of biomass burning across the region. CO mixing ratios at km67 during the wet season are on average 40 ppb higher than at Maxaranguape, which we interpret as CO production from biogenic hydrocarbons, though there may also be some influence from urban areas in eastern Amazon and along the coast. Throughout the wet season in 2009 leading up to the BARCA-B flights in May, CO2 at km67 was elevated by 15-25 ppm relative to CO2 in the marine-air inflow sampled at Maxaranguape, suggesting a net efflux of CO2 during this entire period and consistent with the analysis of airborne observations. |
