Detecting Multiple Ground Contacts in Cloud-to-Ground Lightning Flashes
(American Meteorological Society, 2009)Video recordings of cloud-to-ground (CG) lightning flashes have been analyzed in conjunction with correlated stroke reports from the U.S. National Lightning Detection Network (NLDN) to determine whether the NLDN is capable ... -
CALIPSO/CALIOP Cloud Phase Discrimination Algorithm
(American Meteorological Society, 2009)The current cloud thermodynamic phase discrimination by Cloud-Aerosol Lidar Pathfinder Satellite Observations (CALIPSO) is based on the depolarization of backscattered light measured by its lidar [Cloud-Aerosol Lidar with ... -
Overview of the CALIPSO Mission and CALIOP Data Processing Algorithms
(American Meteorological Society, 2009)The Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) is a two-wavelength polarization lidar that performs global profiling of aerosols and clouds in the troposphere and lower stratosphere. CALIOP is the primary ... -
Thunderstorm Strike Probability Nowcasting
(American Meteorological Society, 2010)To assist in thunderstorm warning, automated nowcasting systems have been developed that detect thunderstorm cells in radar images and propagate them forward in time to generate forecasted threat areas. Current methods, ... -
The Ability of the Small Ice Detector (SID-2) to Characterize Cloud Particle and Aerosol Morphologies Obtained during Flights of the FAAM BAe-146 Research Aircraft
(American Meteorological Society, 2010)The Small Ice Detector mark 2 (SID-2), which was built by the University of Hertfordshire, has been operated by the Met Office on the Facility for Atmospheric Airborne Research (FAAM) BAe-146 aircraft during a large number ... -
Application of Airborne Passive Microwave Observations for Monitoring Inland Flooding Caused by Tropical Cyclones
(American Meteorological Society, 2009)Inland flooding from tropical cyclones is a significant factor in storm-related deaths in the United States and other countries, with the majority of tropical cyclone fatalities recorded in the United States resulting from ... -
Axis Ratios of Water Drops Levitated in a Vertical Wind Tunnel
(American Meteorological Society, 2009)The shapes of falling raindrops are often significantly altered by drop oscillations, complicating dual-polarization radar methods that rely on a predictable, monotonic variation of drop axis ratio α with equivolume drop ... -
Estimating Wind Velocities in Mountain Lee Waves Using Sailplane Flight Data
(American Meteorological Society, 2010)Mountain lee waves are a form of atmospheric gravity wave that is generated by flow over mountain topography. Mountain lee waves are of considerable interest, because they can produce drag that affects the general circulation, ... -
Application of the Multigrid Method to the Two-Dimensional Doppler Radar Radial Velocity Data Assimilation
(American Meteorological Society, 2010)In recent years, the Earth System Research Laboratory (ESRL) of the National Oceanic and Atmospheric Administration (NOAA) has developed a space and time mesoscale analysis system (STMAS), which is currently a sequential ... -
Acoustic Tomography for Scalar and Vector Fields: Theory and Application to Temperature and Wind Estimation
(American Meteorological Society, 2009)Acoustic tomography is a type of inverse problem. The idea of estimating physical quantities that influence sound propagation by measuring the parameters of propagation has proven to be successful in many practical domains, ... -
An Observing System Simulation Experiment (OSSE) for Aerosol Optical Depth from Satellites
(American Meteorological Society, 2009)Monitoring aerosols over wide areas is a scientific challenge with important applications for human health and the understanding of climate. Aerosol optical depth (AOD) measurements from satellites can improve the highly ... -
Vorticity from Line-of-Sight Lidar Velocity Scans
(American Meteorological Society, 2009)A method is presented to compute the spanwise vorticity in polar coordinates from 2D vertical cross sections of high-resolution line-of-sight Doppler wind lidar observations. The method uses the continuity equation to ... -
Top-of-Atmosphere Radiance-to-Flux Conversion in the SW Domain for the ScaRaB-3 Instrument on Megha-Tropiques
(American Meteorological Society, 2009)The earth radiation budget (ERB) is the difference between the solar absorbed flux and the terrestrial emitted flux. These fluxes are calculated from satellite measurements of outgoing shortwave (SW) and longwave (LW) ... -
A Technique for Combining Global Tropical Cyclone Best Track Data
(American Meteorological Society, 2009)Best track data generally consist of the positions and intensities during the life cycle of a tropical cyclone. Despite the widespread interest in the distribution, frequency, and intensity of tropical cyclones worldwide, ... -
