Comparative advantages of Large Aperture Scintillometer and Eddy Covariance instrument for measuring evapotranspiration in irrigated farmlands
Yong Qi, Yan Shen

Paper Summary

The study compared two instruments, Large Aperture Scintillometer (LAS) and Eddy Covariance (EC), for measuring evapotranspiration in farmlands. LAS was found to be reliable and consistent with EC in measuring heat flux and evapotranspiration. Daily and monthly changes in heat flux measurements showed significant agreement between LAS and EC. LAS data can be used to verify estimated evapotranspiration from remote sensing methods.
