PIV measurements of the vector velocity of ESF over Jicamarca

Several techniques are used in order to measure the instantaneous turbulence velocity of the equatorial spread-F (ESF). At Jicamarca, we have two operation modes to study ESF: JULIA-CSR (Coherent Scatter Radar) and JULIA-Imaging. These modes allow us to get vertical and horizontal velocity but not the displacement vector of the turbulence observed. The majority of techniques do not allow us to measure the turbulence displacement. In the present work, we will use imaging data and a particle image velocimetry (PIV) technique to estimate the vector velocity of the spread-F. Preliminary results will be presented as a poster in URSI 2011.
