“…However, when data are limited, errors can be as high as 30% (Carrillo‐Rojas, Silva, Córdova, Célleri, & Bendix, 2016; Córdova et al, 2015). Using an Eddy‐covariance tower, one of the highest in the world, evapotranspiration for páramos was measured, reporting values of around 620 mm yr −1 in southern Ecuador (Carrillo‐Rojas et al, 2019; Ochoa‐Sánchez, Crespo, Carrillo‐Rojas, Marín, & Célleri, 2020; Ochoa‐Sánchez, Crespo, Carrillo‐Rojas, Sucozhañay, & Célleri, 2019). At the same site, net radiation was reported as the primary control of ETa (Ochoa‐Sánchez et al, 2020); while meteorological observations highlighted the role of radiation and air humidity variation in the control of the hydrological system (Carrillo‐Rojas et al, 2019; Ochoa‐Sánchez et al, 2020).…”
