ADMIRARI
ADvanced MIcrowave RAdiometer for Rain Identification

The ADvanced MIcrowave RAdiometer for Rain Identification (ADMIRARI) is an airborne passive microwave radiometer. ADMIRARI measures brightness temperatures at 10.7, 21.0, and 36.5 GHz frequencies along two polarized planes. It is also equipped with a Micro Rain Radar (MRR) to observe rain structure, and a cloud lidar to estimate cloud base. ADMIRARI measurements can be used to determine rain/cloud liquid water path (LWP) and integrated water vapor (IWV). It has a temporal resolution of 1 second and a spatial resolution of 5 degrees.
