In this dataset, we report on five years of energy flux measurements observed by EC over the Guanzhong Plain cropland. The objectives of this study were to (1) characterize seasonal variation in ET and its components in order to identify the important controlling environmental factors; (2) investigate seasonal variation in energy fluxes and determine the energy budget; and (3) assess the effects of crop growth on ET, Bowen ratio (β), the Priestley-Taylor coefficient (α), and canopy conductance (Gc) and examine the relationships between Gc and other surface parameters.
