The [[https://www.unis.no/|University Centre in Svalbard (UNIS)]] is located in Longyearbyen, Svalbard (Norway). Longyearbyen is on the south side of the Adventfjorden. The area is mountainous, featuring seasonal snow cover, a typical tundra system, and glaciers.  Within the CLOUDMAPS project, the Institute of Geophysics and Meteorology cooperates with UNIS and operates a Micro Rain Radar and a Parsivel on the roof of the UNIS building. The measurements are also supported by the Transregional Collaborative Research Centre TR 172 "ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC)³" ([[http://ac3-tr.de|(AC)³]]).

The coordinates of the instruments at UNIS are:
  * Latitude:  78° 13' 21.3" N = 78.22257 °N
  * Longitude: 15° 38' 08.7" E =  15.65241 °E
  * Altitude:  22.5 m ASL (= surface altitude (10 m) + building&pole (12.5 m)) 

===== Scientific Goals =====

"Cloud and Precipitation Observations, Modeling, And Prediction in Svalbard" (CLOUDMAPS) is a collaborative Arctic research network focused on improving the monitoring, understanding, and prediction of clouds and precipitation in Svalbard. It is funded by the Research Council of Norway. By integrating advanced observations, high-resolution modeling, and operational forecasting expertise, the project enhances knowledge of Arctic weather processes, supports improved weather prediction for aviation and society, and strengthens cooperation and data sharing between research institutions in Ny-Ålesund and Longyearbyen. CLOUDMAPS is a joint effort by MET Norway, UNIS, the University of Cologne, and the Norwegian University of Life Sciences.
