TRIPLE FREQUENCY RADAR REFLECTIVITY SIGNATURES OF SNOW: OBSERVATIONS AND COMPARISONS TO THEORETICAL ICE PARTICLE SCATTERING MODELS by
An observation-based study is presented that utilizes aircraft data from the 2003 Wakasa Bay AMSR Precipitation Validation Campaign to assess recent advances in the modeling of microwave scattering properties of realistic ice particles in the atmosphere. Previous work has suggested that a triple-frequency reflectivity framework appears to have utility for identifying key microphysical propertie...
متن کاملEffects of Snow Properties on the Dual Frequency Radar Altimeter Signal of Envisat over the Antarctic Ice-sheet
A unique advantage of the ENVISAT altimeter system is the acquisition in S band as well as the classical Ku band. This S band frequency is designed to measure the ionospheric delay over the ocean surfaces. Over land and ice, however, the returned radar echo differences between the two frequencies are also function of the properties of the sensed medium. This is particularly the case over the An...
متن کاملScientific Preparations for CoRe-H2O, a Dual Frequency SAR Mission for Snow and Ice Observations
The COld REgions Hydrology High-resolution Observatory (CoRe-H2O) satellite mission has been selected for scientific and technical studies within the ESA Earth Explorer Programme. The mission addresses the need for spatially detailed snow and ice observations in order to improve the representation of the cryosphere in climate models and to improve the knowledge and prediction of water cycle var...
متن کاملUse of Dual-wavelength Radar for Snow Parameter Estimates
Use of dual-wavelength radar, with properly chosen wavelengths, will significantly lessen the ambiguities in the retrieval of microphysical properties of hydrometeors. In this paper, a dual-wavelength algorithm is described to estimate the characteristic parameters of the snow size distributions. An analysis of the computational results, made at X and Ka bands (T-39 airborne radar) and at S and...
متن کاملVariable pulse repetition frequency for the GPM dual-frequency radar
In space missions, the delay of a receiving signal to a transmission signal generally spans a few thousands microseconds due to long range observation. An efficient sampling can be achieved by transmitting pulses successively, as schematically shown in Fig. 1. For the later consideration, a catching integer n is to be introduced. In Fig. 1, the catching integer n is set at 11, for which a pulse...
