A combined determination of wind velocities and ozone concentrations for a first measurement of ozone fluxes with a dial instrument during the MEDCAPHOT-TRACE campaign

From a data set collected during the MEDCAPHOT-TRACE field campaign, we demonstrate that ozone fluxes can be determined with a shot-per-shot DIAL instrument operated in the UV spectral region. This is done by the simultaneous reconstruction of ozone concentrations and of wind speeds using the same sample of lidar returns. A correlation scheme is used for the wind velocity retrieval, in which the transport of the spatial inhomogeneities of the aerosol backscattering coefficient along the optical path of the system is analyzed.
