Abstract We present five-year monitoring results of 225 GHz zenith opacity using a tipping radiometer at Thule Air Base (Pituffik), Greenland, where the Greenland Telescope is currently located. The site shows a clear seasonal variation with average opacity lower by a factor of two during winter com...
