RISInfluence of the Subgrid Variability of the Raindrop Size Distribution on Radar Rainfall Estimators
Publisher: American Meteorological Society
Abstract: his work aims at quantifying the variability of the parameters of the power laws used for rain-rate estimation from radar data, on the basis of raindrop size distribution measurements over a typical weather radar pixel. ...
Quantification of the Small-Scale Spatial Structure of the Raindrop Size Distribution from a Network of Disdrometers
Publisher: American Meteorological Society
Abstract: he spatial structure of the raindrop size distribution (DSD) conveys crucial information for reliable quantitative estimation of rainfall using remote sensing techniques. To investigate this question, a network of 16 optical ...
Experimental Quantification of the Sampling Uncertainty Associated with Measurements from PARSIVEL Disdrometers
Publisher: American Meteorological Society
Abstract: he variability of the (rain)drop size distribution (DSD) in time and space is an intrinsic property of rainfall, which is of primary importance for various environmental fields such as remote sensing of precipitation, for ...
Stochastic Space–Time Disaggregation of Rainfall into DSD fields
Publisher: American Meteorological Society
Abstract: stochastic method to disaggregate rain rate fields into drop size distribution (DSD) fields is proposed. It is based on a previously presented DSD simulator that has been modified to take into account prescribed block-averaged ...
An Extended Kalman Filter Framework for Polarimetric X-Band Weather Radar Data Processing
Publisher: American Meteorological Society
Abstract: he different quantities measured by dual-polarization radar systems are closely linked to each other. An extended Kalman filter framework is proposed in order to make use of constraints on individual radar observables that ...
Invariance of the double-moment normalized raindrop size distribution through 3D spatial displacement in stratiform rain
Publisher: American Meteorological Society
Abstract: ouble-moment normalization of the raindrop size distribution (DSD) summarizes the DSD in a compact way, using two of its statistical moments and a ?generic? double-moment normalized DSD function. We present results of an ...
Small-Scale Variability of the Raindrop Size Distribution and Its Effect on Areal Rainfall Retrieval
Publisher: American Meteorological Society
Abstract: he drop size distribution (DSD) describes the microstructure of liquid precipitation. The high variability of the DSD reflects the variety of microphysical processes controlling raindrop properties and affects the retrieval ...
Errors and Uncertainties in Microwave Link Rainfall Estimation Explored Using Drop Size Measurements and High-Resolution Radar Data
Publisher: American Meteorological Society
Abstract: Microwave links can be used for the estimation of path-averaged rainfall by using either the path-integrated attenuation or the difference in attenuation of two signals with different frequencies and/or polarizations. Link ...
A Comparison between the GPM Dual-Frequency Precipitation Radar and Ground-Based Radar Precipitation Rate Estimates in the Swiss Alps and Plateau
Publisher: American Meteorological Society
Abstract: he Global Precipitation Measurement (GPM) mission Dual-Frequency Precipitation Radar (DPR) provides a unique set of three-dimensional radar precipitation estimates across much of the globe. Both terrain and climatic ...
Nonstationarity in Intermittent Rainfall: The “Dry Drift”
Publisher: American Meteorological Society
Abstract: particular aspect of the nonstationary nature of intermittent rainfall is investigated. It manifests itself in the fact that the average rain rate varies with the distance to the surrounding dry areas. The authors call ...
