RISData Retrieval Algorithms for Validating the Optical Transient Detector and the Lightning Imaging Sensor
Publisher: American Meteorological Society
Abstract: A linear algebraic solution is provided for the problem of retrieving the location and time of occurrence of lightning ground strikes from an Advanced Lightning Direction Finder (ALDF) network. The ALDF network measures ...
Dynamic Similarity in Turbine Deposition Testing and the Role of Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The role of absolute pressure in deposition testing is reviewed from first principles. Relevant dimensionless parameters for deposition testing are developed and dynamic similarity conditions are assessed in detail. Criteria ...
A Low-Noise, Microprocessor-Controlled, Internally Digitizing Rotating-Vane Electric Field Mill for Airborne Platforms
Publisher: American Meteorological Society
Abstract: This paper reports on a new generation of aircraft-based rotating-vane-style electric field mills designed and built at NASA?s Marshall Space Flight Center. The mills have individual microprocessors that digitize the ...
North Alabama Lightning Mapping Array (LMA): VHF Source Retrieval Algorithm and Error Analyses
Publisher: American Meteorological Society
Abstract: Two approaches are used to characterize how accurately the north Alabama Lightning Mapping Array (LMA) is able to locate lightning VHF sources in space and time. The first method uses a Monte Carlo computer simulation to ...
