MAARSY – the new MST radar on Andøya: first results of spaced antenna andDoppler measurements of atmospheric winds in the troposphere and mesosphere using a partial array

[摘要] MST radars have been used to study the troposphere, stratosphere andmesosphere over decades. These radars have proven to be a valuable tool toinvestigate atmospheric dynamics. MAARSY, the new MST radar at the island ofAndøya uses a phased array antenna and is able to perform spaced antennaand Doppler measurements at the same time with high temporal and spatialresolution. Here we present first wind observations using the initialexpansion stage during summer 2010. The tropospheric spaced antenna andDoppler beam swinging experiments are compared to radiosonde measurements,which were launched at the nearby Andøya Rocket Range (ARR). Themesospheric wind observations are evaluated versus common volume meteor radarwind measurements. The beam steering capabilities of MAARSY are demonstratedby performing systematic scans of polar mesospheric summer echoes (PMSE)using 25 and 91 beam directions. These wind observations permit to evaluatethe new radar against independent measurements from radiosondes and meteorradar measurements to demonstrate its capabilities to provide reliable winddata from the troposphere up to the mesosphere.
