Balanço de energia e coeficiente de cultura da cana-de-açúcar por dois métodos micrometeorológicos

Abstract: Objetivou-se analisar os componentes do balanço de energia obtidos pelos métodos das correlações turbulentas (EC) e da razão de Bowen (BERB), e determinar a evapotranspiração e o coeficiente de cultura da cana-de-açúcar irrigada por gotejamento subsuperficial sob as condições climáticas do Submédio do Vale do São Francisco. Para tanto, densidades de fluxos de calor latente e sensível foram medidas sobre um cultivo ao longo do ciclo de produção durante o período de novembro de 2010 a outubro de 2011. Com os res… Show more

“…Applying the data validity analysis criterion proposed by Perez et al (1999) led to a data rejection of 42% from a total of 618 observations. These results agree with similar percent of filtered Bowen ratio data from several studies (Perez et al 1999;Peacock and Hess 2004;Carmo et al 2018). The highest proportion of the rejections was observed at night (Figure 2a), whereas at daytime inconsistent data were only observed in the early morning and late afternoon, and all the data at 18:00 local time were filtered (Figure 2a).…”
