Short summary
In July 2016, a new ground-based 22 GHz spectrometer for measuring lower and middle atmospheric water vapor was installed at the Thule High Arctic Atmospheric Observatory located at Thule Air Base (76.5° N, 68.8° W), Greenland. The spectrometer, VESPA-22, is designed to operate automatically with little maintenance. The intercomparison between VESPA-22 dataset and the satellite-based Microwave Limb Sounder dataset shows an average difference within 1.4 % up to 60 km altitude.
