Methods were tested and advanced for rainfall rate estimation from single and dual polarization radars. For the dual polarization radars, a further advanced approach based on the Specific Differential Phase data has led to improved rainfall estimates. This was developed by partners from TU Delft.

Drop clustering was characterized with the help of reconstructed fields from ground measurements performed with a 2D-video disdrometer. The influence of this effect on radar measurement was quantified. This was developed by partners from ENPC.

A morphological scale invariant comparison tool was developed to evaluate the output of various radar rainfall estimation methods. This was developed by partners from ENPC.

At the UK, the Met Office and Imperial College London developed and evaluated a super-resolution C-band radar product.
