ADvanced MIcrowave RAdiometer for Rain Identification
The ADMIRARI (ADvanced MIcrowave RAdiometer for Rain Identification), created by Radiometer Physics GmbH, is a passive microwave radiometer designed to measure water vapor, cloud and liquid rain water with a temporal resolution of 1 second and a spatial resolution of 5°. The ADMIRARI measures brightness temperatures at 10.7, 21.0 and 36.5 GHz frequencies and at two polarized planes (H and V). The radiometer is equipped with two auxiliary active instruments: a Micro Rain Radar (MRR) at 24.1 GHz frequency for rain structure observation and a cloud lidar at 920 nm wavelength for cloud base estimation. The radiometer typically provides rain/cloud liquid water path (LWP) and integrated water vapor (IWV), including total LWP and IWV for low water content cases.
