| Zusammenfassung |
In this work, we describe an efficient approach for wind retrieval
from dual Doppler radar data. The approach produces a gridded field
that not only satisfies the observations, but also satisfies the anelastic
mass continuity equation.
The method is based on the so-called three-dimensional
variational approach to the retrieval of wind fields
from radar data. The novelty consists in separating the task into
steps that reduce the amount of data processed by the global minimization
algorithm, while keeping the most relevant information from the radar
observations. The method is flexible enough to incorporate
observations from several radars, accommodate complex sampling
geometries, and readily include dropsonde or sounding observations
in the analysis.
We demonstrate the usefulness of our method by analyzing a real case
with data collected during the TPARC/TCS-08 field campaign. |
