The objectives of the Multifrequency Imaging Microwave Radiometer
(MIMR) instrument are to provide measurements of (1) precipitation
rates, (2) atmospheric cloud water and water vapor, (3) sea surface
roughness and sea surface temperature, (3) soil moisture, (4) global
snow and ice cover, and (5) wind speed. The MIMR operates at 6
frequencies, each with horizontal and vertical polarizations: 6.8,
10.65, 18.7, 23.8, 36.5, and 90 GHz. MIMR employs nine feedhorns
yielding 20 available channels. The instrument is designed to have a
cross-track swath of 1400-km at an incidence angle of 50 degrees and
is expected to provide a 3-day global coverage of the
Earth. Resolution in the 20 channels is from 60 to 5-km with a 1 to 2
K accuracy. MIMR is scheduled to be launched on the EOS PM series of
spacecraft beginning in 2000.
The MIMR Team Leaders are Dr. Roy S. Spencer and Dr. Christopher Readings.
