Maize Evapotranspiration (Maize ET)

Current research focus

A main research finding is that models have a huge range in their ability to simulate ET, as compared to eddy covariance data from Ames, Iowa. Much of the variation was traced to their simulations of “potential” ET. Surprisingly, among the best models, some were simple and some were complex. To further elucidate the best approaches for simulating ET and improving the models, a second round of inter-comparisons is being initiated. This time better datasets will be used which include eddy covariance data from Mead, NE and lysimeter data from Bushland, TX.
