An international ACTRIS calibration campaign for cloud radars is taking place at Cabauw meteorological site during the full month of October 2021. Two cloud radars (dual-frequency and single frequency), which are parts of the Ruisdael National Observatory and the BASTA cloud radar from France are used to evaluate different calibration techniques. The results of this investigation are expected to be shared and brought to other European cloud radars.
