(American Meteorological Society, 2007)The focus of this paper is on the numerical solution of the stochastic collection equation?stochastic breakup equation (SCE?SBE) describing the evolution of raindrop spectra in warm rain. The drop size distribution (DSD) ... -
Uncertainties in Air Toxics Calculated by the Dispersion Models AERMOD and ISCST3 in the Houston Ship Channel Area
(American Meteorological Society, 2007)The uncertainties in simulations of annually averaged concentrations of two air toxics (benzene and 1,3-butadiene) are estimated for two widely used U.S. air quality models, the Industrial Source Complex Short-Term, version ... -
Year-Round Observation of Longwave Radiative Flux Divergence in Greenland
(American Meteorological Society, 2007)Longwave radiative flux divergence within the lowest 50 m of the atmospheric boundary layer was observed during the Eidgenössische Technische Hochschule (ETH) Greenland Summit experiment. The dataset collected at 72°35?N, ... -
A MODIS Dual Spectral Rain Algorithm
(American Meteorological Society, 2007)The Moderate Resolution Imaging Spectroradiometer (MODIS) dual spectral rain algorithm (MODRA) is developed for rain retrievals over the northern midlatitudes. The reflectance of the MODIS water vapor absorption channel ... -
The Characterization of Ice Cloud Properties from Doppler Radar Measurements
(American Meteorological Society, 2007)The paper describes an original method that is complementary to the radar?lidar algorithm method to characterize ice cloud properties. The method makes use of two measurements from a Doppler cloud radar (35 or 95 GHz), ... -
Development and Application of a Multipollutant Model for Atmospheric Mercury Deposition
(American Meteorological Society, 2007)A multipollutant model, the Community Multiscale Air Quality model paired with the Model of Aerosol Dynamics, Reaction, Ionization, and Dissolution (CMAQ-MADRID), is extended to include a comprehensive treatment of mercury ... -
Using CMAQ for Exposure Modeling and Characterizing the Subgrid Variability for Exposure Estimates
(American Meteorological Society, 2007)Atmospheric processes and the associated transport and dispersion of atmospheric pollutants are known to be highly variable in time and space. Current air-quality models that characterize atmospheric chemistry effects, for ... -
A Combined Local and Nonlocal Closure Model for the Atmospheric Boundary Layer. Part II: Application and Evaluation in a Mesoscale Meteorological Model
(American Meteorological Society, 2007)A new combined local and nonlocal closure atmospheric boundary layer model called the Asymmetric Convective Model, version 2, (ACM2) was described and tested in one-dimensional form and was compared with large-eddy simulations ... -
Sand Flux Simulations at a Small Scale over a Heterogeneous Mesquite Area of the Northern Chihuahuan Desert
(American Meteorological Society, 2007)Within areas of the Chihuahuan Desert dominated by honey mesquite bushes (Prosopis glandulosa), soil erosion causes open eroded patches and the formation of large coppice dunes. The airflow patterns around the dunes and ... -
Quantitative Ice Accretion Information from the Automated Surface Observing System
(American Meteorological Society, 2007)Freezing precipitation is a persistent winter weather problem that costs the United States millions of dollars annually. Costs and infrastructure disruption may be greatly reduced by ice-storm warnings issued by the National ... -
A Combined Local and Nonlocal Closure Model for the Atmospheric Boundary Layer. Part I: Model Description and Testing
(American Meteorological Society, 2007)The modeling of the atmospheric boundary layer during convective conditions has long been a major source of uncertainty in the numerical modeling of meteorological conditions and air quality. Much of the difficulty stems ... -
Examining Photolysis Rates with a Prototype Online Photolysis Module in CMAQ
(American Meteorological Society, 2007)A prototype online photolysis module has been developed for the Community Multiscale Air Quality (CMAQ) modeling system. The module calculates actinic fluxes and photolysis rates (j values) at every vertical level in each ... -
Multiview Cloud-Top Height and Wind Retrieval with Photogrammetric Methods: Application to Meteosat-8 HRV Observations
