Description
| - The Bowen ratio and the Monin-Obukhov similarity principles are based on the assumption that the eddy diffusivities for temperature and humidity are equal to each other under all atmospheric stratifications within turbulent surface boundary layer. However, several authors reported that this equality was violated under advective inversion or during the non-stationary conditions due to clouds passing by and sudden change of wind speed and direction. The inequality of the eddy diffusivity can lead to errors in the energy partitioning estimates by gradient techniques like the Bowen ratio energy balance (BREB) and the aerodynamical method, or methods based on residual energy balance such as the Penman-Monteith or Priestley-Taylor models. This study investigates two seasons of simultaneous measurement by eddy covariance (EC) and BREB above a high density poplar plantation at the Domaninek locality. The direct measurement of eddy diffusivities by EC is reinvestigating the validity of the long term measurement (since 2008) by BREB. Results showed unequal exchange coefficients with their mean 0.31 to 0.35 m2 s-1 for 2011 and 2012, respectively, favouring the transport of latent heat. This might be explained by the different footprints of the BREB and EC methods, an undeveloped internal boundary layer or instrumental errors.
