A new polarimetric scheme for attenuation correction at C band
نویسندگان
چکیده
A long-standing problem of attenuation correction at shorter weather radar wavelengths can be efficiently resolved by using measurements of differential phase ΦDP if the radar is polarimetrically upgraded. Original polarimetric method for attenuation correction by Bringi et al. (1990) stipulates that the ratio αh between specific attenuation Ah and specific differential phase KDP does not vary much for a particular radar wavelength. This assumption, however, is not valid at C band in the presence of large drops associated with anomalously high differential reflectivity ZDR. Several modifications of a dual-polarization rain profiling algorithm have been suggested to address this issue (Carey et al. 2000; Bringi et al. 2001; Lim and Chandrasekar 2006).

Polarimetric Radar Rainfall Estimation at X-band: Evaluation of Attenuation Correction
The most commonly used polarimetric radar measurements in rainfall estimation are the reflectivity factor, usually at horizontal polarization (Zh), differential reflectivity (Zdr) and specific differential propagation phase (Kdp). Based on the above three measurements, a number of algorithms have been derived in the literature to estimate rainfall (see Bringi and Chandrasekar, 2001 for a summar...

There is a renewed interest in the use of X-band weather radars, due to specific advantages such as applications to rainfall estimation in light rain, monitoring of sensitive areas that are inadequately covered by operational radar networks as well as the radar network concept introduced by the Center for Collaborative Adaptive Sensing of the Atmosphere (CASA) (Chandrasekar et al. 2004). The us...

This study proposes investigation of new attenuation correction and microphysical retrieval methods for X-band polarimetric radar (XPOL). It will concentrate on exploring the dependence of the retrieval on raindrop size distribution variability, and its sensitivity with respect to the selection of oblateness-size relation (or axial ratio) and maximum diameter limit. Variations in the assumed fo...
متن کاملC-band dual polarization radar retrieval of rainfall: application of an iterative technique with embedded neural-network
Polarimetric radar measurements at C-band require correction for propagation effects before using them for rainfall retrieval. Since differential phase shift Kdp is affected by the spatial variation of the backscattering differential phase shift δ, a new neural-network estimation technique is applied to remove δ effects on Kdp estimate. In this study we also explore a new hybrid iterative techn...
