 ===== Principle =====
-**JOYRAD-10** is a vertically pointing X-Band Doppler cloud radar MIRA-10 manufactured by [[https://metek.de/|METEK GmbH]]. It is installed at the Forschungszentrum Jülich as part of [[http://cpex-lab.de/cpex-lab/EN/Home/JOYCE-CF/JOYCE-CF_node.html|JOYCE]].
+**JOYRAD-10** is a vertically pointing X-Band Doppler cloud radar MIRA-10 manufactured by [[https://metek.de/|METEK GmbH]]. It is located at the Forschungszentrum Jülich as part of [[http://cpex-lab.de/cpex-lab/EN/Home/JOYCE-CF/JOYCE-CF_node.html|JOYCE]]. It has been installed as part of the Emmy-Noether research group [[https://geomet.uni-koeln.de/forschung/en-optimice|OPTIMICE]] led by Stefan Kneifel in order to perform triple-frequency radar observations in combination with Ka- and W-Band radars.
