MAARSY - the new MST radar on Andøya/Norway
The Leibniz-Institute of Atmospheric Physics in Kühlungsborn, Germany (IAP) is installing a new powerful VHF radar on the North-Norwegian island Andøya (69.30° N, 16.04° E) in 2009/2010. The new Middle Atmosphere Alomar Radar System (MAARSY) replaces the existing ALWIN radar which has been operated...

Each individual antenna is connected to its own transceiver with independent phase control and a scalable output up to 2 kW.

The high flexibility of the new system allows classical Doppler beam swinging as well as experiments with simultaneously formed multiple beams and the use of modern interferometric applications for improved studies of the Arctic atmosphere from the troposphere up to the lower thermosphere with high spatiotemporal resolution. © 2010 Author(s). publishedVersion Article in Journal/Newspaper Andøya Arctic LeibnizOpen (The Leibniz Association) |
