The boundary layer field experiment in the area of Terranova Bay, during the summer 1994-95

To study the characteristics of the air flow in a confluence region, two measurement stations have been set up in the area of Terranova Bay during the summer campaign 1994-95: one on the Reeves Never (at 1200 m ASL) and another one on the Nansen Ice Sheet close to the confluence of the Reeves Glacier. Both the stations were equipped with a triaxial Doppler sodar, and with several fast response sensors to evaluate the characteristics of the turbulent fluxes over a complex orographic area. In this work the description of the experiment is given, and a first attempt to correlate different sensor measurements at the Nansen Ice Sheet station is presented. Good agreement is found between the wind measurements obtained by sodar and sonic anemometers. The differences recorded in the sonic anemometer and sodar momentum flux estimates need further investigation.
