Testing IWC Retrieval Methods Using Radar and Ancillary Measurements with In Situ Data

Cirrus Cloud Microphysical Property Retrieval Using Lidar and Radar Measurements. Part I: Algorithm Description and Comparison with In Situ Data

A retrieval algorithm is described to estimate vertical profiles of cirrus-cloud ice water content (IWC) and general effective size Dge from combined lidar and radar measurements. In the algorithm, the lidar extinction coefficient s is parameterized as s 5 IWC[a0 1 (a1/Dge)] and water equivalent radar reflectivity factor Ze is parameterized as Ze 5 C9(IWC/ri) , where a0, a1, C9, and b are const...

data mining rules and classification methods in insurance: the case of collision insurance

assigning premium to the insurance contract in iran mostly has based on some old rules have been authorized by government, in such a situation predicting premium by analyzing database and it’s characteristics will be definitely such a big mistake. therefore the most beneficial information one can gathered from these data is the amount of loss happens during one contract to predicting insurance ...

Cloud Microphysics Retrieval Using S-Band Dual-Polarization Radar Measurements

The recent deployment of multiparameter, polarimetric radars provides the impetus for development of microphysical retrievals. The primary objective of this paper is to describe a particle classification technique that makes use of polarimetric radar observations. The particle classification technique is computationally simple enough to be implemented for real-time research and operational fiel...

Hail detection methods using radar data

Different methods for hail detection are presented in the seminar. The presented methods use radar reflectivity measurements to determine the occurrence of hail. We compared observations made on meteorological stations, radar derived product developed by Faculty of mathematics and physics (FMF) and radar derived product VIL (Vertically integrated liquid). Comparison is performed for the period ...
