The general interest in the potential use of the mm and sub-mm frequencies
up to 425 GHz resolution from geostationary orbit is increasing due to the
fact that the frequent time sampling and the comparable spatial resolution
relative to the "classical" (≤89 GHz) microwave frequencies would
allow the monitoring of precipitating intense events for the assimilation of
rain in now-casting weather prediction models.
In this paper, we use the simulation of a heavy precipitating event in front
of the coast of Crete island (Greece) performed by the University of
Wisconsin - Non-hydrostatic Modeling System (UW-NMS) cloud resolving model
in conjunction with a 3D-adjusted plane parallel radiative transfer model to
simulate the upwelling brightness temperatures (TB's) at mm and sub-mm
frequencies. To study the potential use of high frequencies, we first
analyze the relationships of the simulated TB's with the microphysical
properties of the UW-NMS simulated precipitating clouds, and then explore
the capability of a Bayesian algorithm for the retrieval of surface rain
rate, rain and ice water paths at such frequencies. |
