Micro Rain Radar Measurements of Rainfall in Madrid

Inhalt:
A vertically pointing Doppler radar at 24.1 GHz, or Micro Rain Radar (MRR), has been installed at Universidad Politécnica de Madrid as part of the experimental set-up for propagation measurements that includes a tipping-bucket rain gauge and a disdrometer. The Doppler spectra measured by the MRR are converted into profiles of drop size density distributions. The MRR provides equally profiles of radar reflectivity, rainfall rate or terminal velocity, which can be useful to identify and analyse propagation effects produced by rain, once its behaviour has been assessed. With this aim, a study of MRR measurements is being performed. The analysis of MRR data corresponding to two different rainfall events, whose results are presented here, reveals characteristics in agreement with the stratiform or convective type of event.
