A Embrapa Arroz e Feijão, a Universidade Federal de Goiás e a Emater-GO, sob a coordenação da primeira, elaboraram projeto buscando propor alternativas de recuperação de áreas degradadas com espécies nativas e potencialmente utilizáveis para exploração econômica e sustentável, como, por exemplo, a produção de agroenergia, frutos nativos, madeira, carvão, fitoterápicos, etc., em áreas de pequenos produtores familiares da região de Caiapônia, GO. |

The failure of the Monin?Obukhov Similarity Theory (MOST) in the roughness sublayer is a major prob-lem for the estimation of fluxes over tall forests, whenever indirect methods that rely on MOST, suchas flux-gradient or the variance method, are involved. While much research focuses on micrometeoro-logical measurements over temperate-climate forests, very few studies deal with such measurementsover tropical forests. In this paper, we show evidence that some similarity functions over the Amazonforest are somewhat different from temperate forests. Comparison of the nondimensional scalar gradi-ents canonical values for the inertial sublayer with our measurements in the roughness sublayer showedsmaller deviations than what is usually reported for temperate forests. Although the fluxes of watervapor and CO2derived from mean profiles show considerable scatter when compared with the eddycovariance measurements, using calibrated dimensionless gradients it is possible to estimate their meandaily cycle during the period of measurement (36 days in May and June, transition between rainy anddry season). Moreover, since mean ozone profiles were available, although without the correspondingeddy covariance measurements, mean daily ozone fluxes were calculated with the flux-gradient method,yielding a nighttime value of −0.05 and a daily peak of −0.45μgm−2s−1 (−1.04 and −9.37nmolm−2s−1, respectively). These values are comparable to previously measured fluxes in the literature for the Amazonforest.
