Interpretive Summary:

Technical Abstract: Evapotranspiration was continuously measured by an array of eddy covariance systems and large weighting lysimeter in a cotton field in Bushland, Texas. The advective divergence from both horizontal and vertical directions were measured through profile measurements above canopy. All storage terms were integrated from the depth of soil heat flux plate to the height of eddy covariance measurement. Therefore, an analysis between the eddy covariance system and large weighing lysimeter was spectrally conducted on hourly and daily basis for a growing season. Our results for the discrepancy between eddy covariance towers and the lysimeter will be discussed in terms of advection occurance and storage contributions.
