Effetto delle correzioni dei dati misurati da stazioni eddy covariance sulla stima dei flussi evapotraspirativi

Eddy covariance measurements have to be adjusted to correctly estimate the evapotranspiration fluxes. The main objective of this work is to analyze instrumental and physical corrections which are connected to an inappropriate sensors position or fluid (air) physical propriety. The data have been measured by two micrometeorological stations located at Landriano (PV) and Livraga (LO) in the Po Valley. The results show that the physical corrections are dominant in respect to instrumental corrections generating an energy balance improvements of about 20%.
