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 ...
CHARGE DENSITIES IN THE IONOSPHERE FROM RADIO DOPPLER DATA
Publisher: American Meteorological Society
Abstract: A method is described whereby the directly observable radial velocities of a missile relative to a ground receiver?both in a radio-Doppler electronic system of tracking?may be compared to radial velocities determined by ...
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 ...
Capacity Analysis of Pedestrian Treatments at Large Arterial Intersections and Comparison with a Lane-Equivalent, Small Intersection Gridded Network
Publisher: American Society of Civil Engineers
Abstract: Intersections of major six-lane arterial roadways and minor four-lane arterial roadways are becoming increasingly common across the United States, in part due to the proliferation of hierarchical street design. Such ...
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 ...
Cyclic Torsion Tests of Concrete Box Columns
Publisher: American Society of Civil Engineers
Abstract: Stiffness reduction and material energy dissipation of reinforced concrete box‐members have been investigated experimentally under cyclic torsional loading. Six specimens were tested; four in pure torsion and two with axial ...
