| Zusammenfassung |
| A large set of ground-based multi-frequency microwave
radiometric simulations and measurements during different precipitation
regimes are analysed. Simulations are performed for a set of frequencies
from 22 to 60 GHz, representing the channels currently available on an
operational ground-based radiometric system. Results are illustrated in
terms of comparisons between measurements and model data in order to show
that the observed radiometric signatures can be attributed to rainfall
scattering and absorption. An inversion algorithm has been developed, basing
on the simulated data, to retrieve rain rate from passive radiometric
observations. As a validation of the approach, we have analyzed radiometric
measurements during rain events occurred in Boulder, Colorado, and at the
Atmospheric Radiation Measurement (ARM) Program's Southern Great Plains
(SGP) site in Lamont, Oklahoma, USA, comparing rain rate estimates with
available simultaneous rain gauge data. |
