34th Conference on Radar Meteorology


Wind Retrieval from airborne Doppler radar

Carlos López Carrillo, New Mexico Tech, Socorro, NM; and D. J. Raymond

We present a novel approach to wind retrieval from airborne Doppler

radar. Our approach is a two-step process.

The first step is a generalization of a co-planar fit of radial

velocities. This step produces synthetic particle

velocities on a regular grid. These synthetic velocities are defined

on the best co-plane at each grid point. Furthermore, an estimate of

the error associated with each velocity component is also calculated.

During the second step, we search for a wind field that satisfies

mass continuity and minimizes the misfit with the gridded

particle velocities. This step is cast as an optimization problem,

which is solved using a multigrid technique.

This approach has two key advantages. 1) It reduces the amount of

information processed by the minimization algorithm without discarding

high elevation angle measurements. 2) The multigrid technique allows

faster convergence rates in comparison with more conventional

optimization algorithms, especially for larger or denser grids.

We showcase this approach with data collected during

TCS-08 field campaign using the eldora radar.
