Evaluation of Doppler radar velocity estimators

Three-Dimensional Simple Adjoint Velocity Retrievals from Single-Doppler Radar

In this paper, the original simple adjoint method of Qiu and Xu is improved and tested for retrieving the 3D storm-scale wind field from single-Doppler radar data. The method incorporates single-radar data and background fields, along with a dynamical constraint, smoothness, and anelastic mass continuity constraint, in a cost function. The minimization of the cost function, with the desired fit...

Wind velocity observation with a CW Doppler radar

We study the problem of gathering information about wind velocity from continuous-wave clear-air Doppler radar measurements. The radar is assumed to be a monostatic fixed-frequency Doppler radar, and the wind velocity as well as the reflectivity are modeled as random fields with statistical parameters depending on the altitude. We seek to reconstruct the hodograph curve of the wind profile, i.e...

Evaluation of Mass Flux Representations of Vertical Velocity Fluctuations in Continental Stratus Clouds Using a mm-Wavelength Doppler Radar

A cloud mass flux representation of the vertical turbulent fluxes provides a physical framework for understanding the effects of shallow convection in maintaining the vertical structure of the boundary layer. This approach is based on the assumption that coherent updrafts and downdraft structures are responsible for most of the turbulent transport. Previous evaluations of mass flux parameteriza...
