Short summary
Interferometric radar meteorology (IRM) is a new technique for meteorological applications and atmospheric studies. It can be used to study the water vapour content in the atmosphere with a spatial resolution of 20 m and an accuracy of about 2 mm. This high spatial resolution of water vapour distribution can be important for short-scale weather forecasting and climate research.
