Researchers studied evapotranspiration in the Central Andes of Peru using eddy covariance techniques and empirical equations. They found that evapotranspiration in the region is influenced by water and energy availability, with higher evapotranspiration during the wet season and lower during the dry season. Evapotranspiration is closely linked to factors like solar radiation and soil moisture. The Priestley-Taylor equation performed well in estimating evapotranspiration variability, but struggled during the dry season due to a lack of consideration for soil water content. Including soil water content in calculations could improve estimates of evapotranspiration in the region.
