The Impact of Nudging in the Meteorological Model for Retrospective Air Quality Simulations. Part II: Evaluating Collocated Meteorological and Air Quality Observations
(American Meteorological Society, 2008)For air quality modeling, it is important that the meteorological fields that are derived from meteorological models reflect the best characterization of the atmosphere. It is well known that the accuracy and overall ... -
Effects of Atmospheric Turbulence on Ballistic Testing
(American Meteorological Society, 2008)The effects of atmospheric turbulence on munition target scatter are determined from numerical simulations of ballistic trajectories through many realizations of realistic simulated turbulent wind fields. A technique is ... -
Near-Real-Time Applications of CloudSat Data
(American Meteorological Society, 2008)Within 2 months of its launch in April 2006 as part of the Earth Observing System A-Train satellite constellation, the National Aeronautics and Space Administration Earth System Science Pathfinder (ESSP) CloudSat mission ... -
Comparisons of Transport and Dispersion Model Predictions of the Joint Urban 2003 Field Experiment
(American Meteorological Society, 2008)For a hazardous material release in a city or densely populated area, effective mitigation requires an understanding of the transport and dispersion of these hazards in the complex urban environment. Improved characterization ... -
The Impact of Nudging in the Meteorological Model for Retrospective Air Quality Simulations. Part I: Evaluation against National Observation Networks
(American Meteorological Society, 2008)It is common practice to use Newtonian relaxation, or nudging, throughout meteorological model simulations to create ?dynamic analyses? that provide the characterization of the meteorological conditions for retrospective ... -
Infrared Continental Surface Emissivity Spectra Retrieved from AIRS Hyperspectral Sensor
(American Meteorological Society, 2008)Atmospheric Infrared Sounder (AIRS; NASA Aqua platform) observations over land are interpreted in terms of monthly mean surface emissivity spectra at a resolution of 0.05 ?m and skin temperature. For each AIRS observation, ... -
Impacts of a New Solar Radiation Parameterization on the CPTEC AGCM Climatological Features
(American Meteorological Society, 2008)The impacts of improved atmospheric absorption on radiative fluxes, atmospheric circulation, and hydrological cycle for long-term GCM integrations are investigated. For these runs the operational version of the Centro de ... -
A Two-Tier Statistical Forecast Method for Agricultural and Resource Management Simulations
(American Meteorological Society, 2008)Simple phase schemes to predict seasonal climate based on leading ENSO indicators can be used to estimate the value of forecast information in agriculture and watershed management, but may be limited in predictive skill. ... -
Linking a Lagrangian Particle Dispersion Model with Three-Dimensional Eulerian Wind Field Models
(American Meteorological Society, 2008)A slightly simplified form of Thomson?s Lagrangian stochastic model (LSM) is presented for dispersion applications in three-dimensional (3D) flow fields. It is found that the Lagrangian velocity of a particle in 3D ... -
A Characterization of Cirrus Cloud Properties That Affect Laser Propagation
(American Meteorological Society, 2008)Future high-altitude laser systems may be affected by cirrus clouds. Laser transmission models were applied to measured and retrieved cirrus properties to determine cirrus impact on power incident on a target or receiver. ... -
Snowfall Retrievals Using Millimeter-Wavelength Cloud Radars
(American Meteorological Society, 2008)It is demonstrated that millimeter-wavelength radars that are designed primarily for cloud studies can be also used effectively for snowfall retrievals. Radar reflectivity?liquid equivalent snowfall rate (Ze?S) relations ... -
Source Inversion for Contaminant Plume Dispersion in Urban Environments Using Building-Resolving Simulations
(American Meteorological Society, 2008)The ability to determine the source of a contaminant plume in urban environments is crucial for emergency-response applications. Locating the source and determining its strength based on downwind concentration measurements, ... -
