 ===== Principle =====
-The cloud radar MIRA is a Doppler radar that transmits a linear polarized signal at 35.5 GHz and receives co- and cross-polarized signals simultaneously. In this way, vertical profiles of reflectivity, Doppler velocity, Doppler spectral width and of linear depolarization ratio are detected from 150 m to 15 km above ground. Given these measurements, information on the macrophysical (cloud boundaries, type of cloud particles) and microphysical (e.g., liquid and ice water content) properties of the detected cloud can be derived. The radar can be operated in a vertically pointing mode but also has scanning capabilities in order to better capture the 3-dimensional structure of the cloud.
