| Summary: | <p>Recently, the MMARIA (Multi-static, Multi-frequency Agile Radar for
Investigations of the Atmosphere) concept of a multi-static VHF meteor radar
network to derive horizontally resolved wind fields in the mesosphere–lower
thermosphere was introduced. Here we present preliminary results of the
MMARIA network above Eastern Germany using two transmitters located at
Juliusruh and Collm, and five receiving links: two monostatic and three
multi-static. The observations are complemented during a one-week campaign,
with a couple of addition continuous-wave coded transmitters, making a total
of seven multi-static links. In order to access the kinematic properties of
non-homogenous wind fields, we developed a wind retrieval algorithm that
applies regularization to determine the non-linear wind field in the altitude
range of 82–98 km. The potential of such observations and the new retrieval
to investigate gravity waves with horizontal scales between 50–200 km is
presented and discussed. In particular, it is demonstrated that horizonal
wavelength spectra of gravity waves can be obtained from the new data set.</p> |
