ADMIRARI (ADvanced MIcrowave RAdiometer for Rain Identification)
is a unique passive microwave radiometer. It was built by
Physics, Meckenheim and delivered to the
Meteorological Institute at the
University of Bonn
in summer 2007.
It is designed to measure water vapor, cloud and rain
liquid water with high temporal (1s) and spatial resolution (5°). The
radiometer is mounted on a trailer
easy transportation and participation in field campaigns.
Additionally it is equipped with two active
instruments, i.e. since 2008 a Micro Rain Radar (MRR) at 24.1
GHz frequency for rain structure observation
and since September 2010 with a cloud Lidar at 920 nm wavelength for
Cloud base estimation. Both active instruments
are fully steerable alike ADMIRARI.
