Dual lidar observations of mesoscale fluctuations of ozone and horizontal winds

Abstract : A case study is presented of 6.5 h of simultaneous colocated stratospheric Differential Absorption Lidar (DIAL) measurements of ozone concentration and Rayleigh-Mie Doppler (RD) lidar measurements of horizontal wind velocity from the Observatoire de Haute Provence (OHP), France (44°N, 6°E). The RD lidar observations reveal a distinct gravity wave motion at ∼12-18 km, while the DIAL data show laminated ozone structures in the same height range. We combine these data to show that advection due to the gravity wave cannot produce the large ozone lamina at ∼14km.
