abstract = "Experimentally characterizing evapotranspiration (ET) in different
biomes around the world is an issue of interest for different
areas of science. ET in natural areas of the Brazilian Pampa biome
has still not been assessed. In this study, the actual ET (ETact)
obtained from eddy covariance measurements over two sites of the
Pampa biome was analyzed. The objective was to evaluate the energy
partition and seasonal variability of the actual ET of the Pampa
biome. Results showed that the latent heat flux was the dominant
component in available energy in both the autumnwinter (AW) and
springsummer (SS) periods. Evapotranspiration of the Pampa biome
showed strong seasonality, with highest ET rates in the SS period.
During the study period, approximately 65% of the net radiation
was used for the evapotranspiration process in the Pampa biome.
The annual mean ET rate was 2.45 mm d\−1. ET did not show
to vary significantly between sites, with daily values very
similar in both sites. The water availability in the Pampa biome
was not a limiting factor for ET, which resulted in a small
difference between the reference ET and the actual ET. These
results are helpful in achieving a better understanding of the
temporal pattern of ET in relation to the landscape of the Pampa
biome and its meteorological, soil, and vegetation
characteristics.",
