MIE LIDAR THESIS

In this study, we discuss in chapter 7 the results of a validation campaign conducted during the period of April to December Horizontal collectors filter paper sheets are also used to measure the terrestrial spray drift. The problem of data inversion is surveyed with emphasis on smoothing methods, statistical analyses, and iterative techniques. Metadata Show full item record.

A discussion of the numerical stability of the solution is also presented. LIDAR systems have applications in many fields, including the measurement of the wind speed and direction, to obtain the concentration of chemical species, in ceilometry height and thickness of clouds. Since its installation in Aprilthe new LIDAR has been used to monitor stratospheric temperatures and aerosol concentrations from 10 to 40 km. This may be explained by stratospheric upwelling, carrying the layer to higher altitude.

The steering of the LIDAR is made by an electromechanical system with two freedom degrees azimuth and elevation.

This investigation will give some useful insight into the local atmospheric dynamics. On the basis of the Mie model, inversion of the data provided by the LIDAR probe is given as a rationale to licar an estimate of the true particle number distribution function in an atmospheric cell.

These variations could be due to relatively fast transient phenomena like gravity waves or planetary waves propagating vertically in the stratosphere. Four poles are shown: The interaction between the laser beam and the aerosol and the atmospheric molecules follow the scattering laws Rayleigh, Mie and Raman.

The SPGL is a varifocal length lens which depends on the temperature of the pipe and the angular velocity at which it spins. Lidar system deployed in the field during a drift measurement Gregorio et al.
