Temporal Patterns of Energy Balance for a Brazilian Tropical Savanna under Contrasting Seasonal Conditions

Table 2

Mean (+95% confidence interval) net radiation (𝑅_𝑛), sensible heat flux (𝐻), latent heat flux (𝐿_𝑒), ground heat flux (𝐺), and the Bowen ratio for the dry and wet seasons and annual cycle in 2009-2010 and 2010-2011. The number of days for each season and year is shown in parentheses. Confidence intervals were calculated using bootstrap randomization techniques (𝑛=1000 iterations).
