Two-Dimensional Video Disdrometer: A Description
Publisher: American Meteorological Society
Abstract: This paper describes the design and operation of a two-dimensional video disdrometer (2DVD) for in situ measurements of precipitation drop size distribution. The instrument records orthogonal image projections of raindrops ...
Wind-Induced Error of Raindrop Size Distribution Measurement Using a Two-Dimensional Video Disdrometer
Publisher: American Meteorological Society
Abstract: The authors investigate a disdrometer that provides information on raindrop size distribution, terminal velocity, and shape using video imaging technology. Two video cameras are enclosed in a large box and provide images ...
Comparison of Drop Size Distribution Measurements by Impact and Optical Disdrometers
Publisher: American Meteorological Society
Abstract: Simultaneous observations made with optical- and impact-type disdrometers were analyzed to broaden knowledge of these instruments. These observations were designed to test how accurately they measure drop size distributions ...
Evaluating NEXRAD Multisensor Precipitation Estimates for Operational Hydrologic Forecasting
Publisher: American Meteorological Society
Abstract: Next-Generation Weather Radar (NEXRAD) multisensor precipitation estimates will be used for a host of applications that include operational streamflow forecasting at the National Weather Service River Forecast Centers ...
High-Resolution Rainfall Estimation from X-Band Polarimetric Radar Measurements
Publisher: American Meteorological Society
Abstract: The paper presents a rainfall estimation technique based on algorithms that couple, along a radar ray, profiles of horizontal polarization reflectivity (ZH), differential reflectivity (ZDR), and differential propagation ...
Lidar-Based Estimation of Small-Scale Rainfall: Empirical Evidence
Publisher: American Meteorological Society
Abstract: A significant scale gap between radar and in situ measurements of rainfall using rain gauges and disdrometers indicates a pressing need for improved knowledge of rainfall variability at the spatial scales below those of ...
Radar Rainfall Estimation for Ground Validation Studies of the Tropical Rainfall Measuring Mission
Publisher: American Meteorological Society
Abstract: This study presents a multicomponent rainfall estimation algorithm, based on weather radar and rain gauge network, that can be used as a ground-based reference in the satellite Tropical Rainfall Measuring Mission (TRMM). ...
Real-Time Flood Forecasting and Information System for the State of Iowa
Publisher: American Meteorological Society
Abstract: he Iowa Flood Center (IFC), established following the 2008 record floods, has developed a real-time flood forecasting and information dissemination system for use by all Iowans. The system complements the operational ...
An Experimental Study of Small-Scale Variability of Radar Reflectivity Using Disdrometer Observations
Publisher: American Meteorological Society
Abstract: Analysis of data collected by four disdrometers deployed in a 1-km2 area is presented with the intent of quantifying the spatial variability of radar reflectivity at small spatial scales. Spatial variability of radar ...
