| Summary: | MST radars have been used to study the troposphere, stratosphere and
mesosphere over decades. These radars have proven to be a valuable tool to
investigate atmospheric dynamics. MAARSY, the new MST radar at the island of
Andøya uses a phased array antenna and is able to perform spaced antenna
and Doppler measurements at the same time with high temporal and spatial
resolution. Here we present first wind observations using the initial
expansion stage during summer 2010. The tropospheric spaced antenna and
Doppler beam swinging experiments are compared to radiosonde measurements,
which were launched at the nearby Andøya Rocket Range (ARR). The
mesospheric wind observations are evaluated versus common volume meteor radar
wind measurements. The beam steering capabilities of MAARSY are demonstrated
by performing systematic scans of polar mesospheric summer echoes (PMSE)
using 25 and 91 beam directions. These wind observations permit to evaluate
the new radar against independent measurements from radiosondes and meteor
radar measurements to demonstrate its capabilities to provide reliable wind
data from the troposphere up to the mesosphere. |
