Our X-band polarimetric radar target simulator was on display at the 11th European Conference in Meteorology and Hydrology in Locarno, Switzerland. After COVID related conference interruptions, it was a great opportunity to catch up with leading weather radar scientists and operational radar meteorologists. As a conference sponsor, we took the chance to make the community aware of our radar calibration technology. From what we saw during the talks and the poster session, there is definitively a need for more accurate observations.
