要約

In this study, we have explored another aspect of surface heterogeneity. This aspect is the time lag of maximum Evapotranspiration (ET) rates between different land-surface types. We have analyzed ET data; from the field experiment conducted near Sidney, Montana-USA. Our analysis shows that ET rates from different surface types not only differ significantly but also maximum ET rates are on the order of an hour different.
