Short summary
This research makes an application of the multifrequency technique (RIM) to the spectral analysis (frequency domain) for both atmospheric and precipitation, especially for precipitation echoes. Various precipitation conditions such as stratiform and convective precipitations were investigated with RIM for the first time. The effectiveness and potential capabilities of RIM in resolving small-scale precipitation and atmosphere structures have been verified by conditional averaging analysis.
