Abstract

V originále

The lidar system employed laser radiation at a wavelength of 355 nm with a power of 9W and a pulse repetition rate of 30 Hz.With this set up and approach, the lidar was able to identify the aerosol plume up to a range of similar to 2.5 km from the source, a farm in northern Germany, in daytime. The measurements confirm that the optical particle properties of the emission plume vary largely with distance from the source and that the maximum particle backscatter coefficient is found away from the source. Within a close-to-horizontal scan (elevation angle of 2.3 degrees), we found a mean particle backscatter coefficient of 1.5.10(-5) m(-1) sr(-1) inside the plume between 1.5 and 2.0 km distance from the source. Subtraction of the mean particle backscatter coefficient of the background aerosol present in this case (4.1.10-6 m(-1) sr(-1)) yields a particle backscatter coefficient of the livestock aerosols of 1.1.10(-5) m(-1) sr(-1).
