abstract = "On the basis of measurements over different surfaces, an inertial
sublayer (ISL), where Monin-Obukhov Similarity Theory applies,
exists above z = 3h, where h is canopy height. The roughness
sublayer is within h < z < 3h. Most studies of the surface layer
above forests, however, are able to probe only a narrow region
above h. Therefore, direct verification of an ISL above tall
forests is difficult. In this study we conducted a systematic
analysis of unstable turbulence characteristics at heights from 40
to 325 m, measured at an 80m, and the recently built 325-m Amazon
Tall Tower Observatory towers over the Amazon forest. Our analyses
have revealed no indication of the existence of an ISL; instead,
the roughness sublayer directly merges with the convective mixed
layer above. Implications for estimates of momentum and scalar
fluxes in numerical models and observational studies can be
significant. Plain Language Summary The Amazon forest interacts
with the atmosphere by emitting and absorbing many substances,
such as carbon dioxide, methane, ozone, and organic compounds,
produced by the vegetation. These substances are very influential
in both the regional and global climates, and until now, the
estimates of their emission and absorption rates are based on
classical theories developed originally over relatively short
vegetation and valid for a region above the ground called the
{"}inertial sublayer.{"} In this work we present evidence,
obtained with the help of measurements from a very tall tower (325
m), that a classical inertial sublayer does not exist over the
Amazon forest. New methods to quantify the emission and absorption
rates, therefore, will be needed to improve their estimates.",
