Remote Sensing of Wind Profiles in the Boundary Layer

Résumé du livre

"This report is a discussion and evaluation of the potential capacities of remote sensing techniques for the measurement of wind profiles in the boundary layer of the atmosphere (i.e., up to heights of about 1.5 km). The wind profile, together with the temperature profile, are the primary meteorological parameters that control the dispersion of pollutants once the have been introduced into the boundary layer, usually close to the surface. to predict this dispersion, accurate information on the wind profile in the boundary layer is required. Standard meteorological radiosonde balloons could be used, but these suffer from the disadvantage that each balloon gives only a single profile, measured along an inclined trajectory through the layer. Typically, such profiles are obtained only every 6 to 12 hours and provide an amount of data seriously inadequate for the understanding and prediction of the future distribution of pollutants. There exists, therefore, a need for a remote wind-sensing device that could measure the wind profile essentially continuously and reveal trends or changes as soon as they occur"--Introduction.
