Joint Observational Research on Nocturnal Atmospheric Dispersion of Aerosols (JORNADA)

Abstract

Four major analyses were conducted using the stable boundary layer JORNADA data. First was the analysis of the movement of instantaneous plumes released from a spray aircraft and continuously scanned with the lidar. Techniques for quantifying the concentrations of aerosols in the drifting plumes were established. The effects on plume dynamics and spread of short time (~seconds) sub-mesoscale events were quantified. The second was an analysis of "wave modified flux and plume dispersion in the stable boundary layer". We showed that the variances of cross-wind velocities and the turbulence kinetic energy calculated without removing the wave signal are greater than those calculated when the wave signal is separated from the turbulence.
