This complexity induces heterogeneity in the surface but also affects lateral movement of carbon dioxide (CO<jats:sub>2<\/jats:sub>) not readily detected by the eddy covariance systems. This study describes such variability using measurements of CO<jats:sub>2<\/jats:sub> along vertical profiles and along a toposequence in a tropical rain forest near Manaus, Brazil.<\/jats:p><jats:p>Seasonal and diurnal variation was recorded, with atmospheric CO<jats:sub>2<\/jats:sub> concentration maxima around dawn, generally higher CO<jats:sub>2<\/jats:sub> build\u2010up in the dry season and stronger daytime CO<jats:sub>2<\/jats:sub> drawdown in the wet season. This variation was reflected all along the toposequence, but the slope and valley bottom accumulated clearly more CO<jats:sub>2<\/jats:sub> than the plateaus, depending on atmospheric stability. Particularly during stable nights, accumulation was along lines of equal altitude, suggesting that large amounts of CO<jats:sub>2<\/jats:sub> are stored in the valleys of the landscape. Flushing of this store only occurs during mid\u2010morning, when stored CO<jats:sub>2<\/jats:sub> may well be partly transported back to the plateaus. It is clear that, for proper interpretation of tower fluxes in such complex and actively respiring terrain, the horizontal variability of storage needs to be taken into account not only during the night but also during the mornings.<\/jats:p>","DOI":"10.1890\/06-0982.1","type":"journal-article","created":{"date-parts":[[2008,8,13]],"date-time":"2008-08-13T17:31:46Z","timestamp":1218648706000},"page":"1406-1419","source":"Crossref","is-referenced-by-count":50,"title":["NOCTURNAL ACCUMULATION OF CO<sub>2<\/sub> UNDERNEATH A TROPICAL FOREST CANOPY ALONG A TOPOGRAPHICAL GRADIENT"],"prefix":"10.1002","volume":"18","author":[{"given":"Alessandro C.","family":"de Ara\u00fajo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bart","family":"Kruijt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio D.","family":"Nobre","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albertus J.","family":"Dolman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maarten J.","family":"Waterloo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eddy J.","family":"Moors","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana S.","family":"de Souza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,9]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-2504(08)60018-5"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0168-1923(01)00244-1"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1024168428135"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2486.2003.00629.x"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.2307\/1938896"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1002039610790"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004420050140"},{"issue":"20","key":"e_1_2_8_9_1","doi-asserted-by":"crossref","first-page":"8076","DOI":"10.1029\/2000JD000284","article-title":"Seasonality in CO2 and H2O flux at an eastern Amazonian rain forest","volume":"107","author":"Carswell F.
