A MODIS Dual Spectral Rain Algorithm
Sep 01, 2007; ... ABSTRACT 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 at 1.38 µm (R^sub 1.38 µm^) has a potential to represent ...
Enhancement of Afternoon Thunderstorm Activity by Urbanization in a Valley: Taipei
Sep 01, 2007; ... ABSTRACT Located in northern Taiwan, Taipei is a metropolis surrounded by hills and mountains that form a basin in which two river valleys funnel the surface airflow of this basin to the open sea. Because of the southwest monsoon, summer is a dry season in northern Taiwan but is the ...
Development and Application of a Multipollutant Model for Atmospheric Mercury Deposition
Sep 01, 2007; ... ABSTRACT 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 processes and is applied to the simulation of the ...
Using CMAQ for Exposure Modeling and Characterizing the Subgrid Variability for Exposure Estimates
Sep 01, 2007; ... ABSTRACT 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 example, the Community Multiscale Air Quality model ...
Uncertainties in Air Toxics Calculated by the Dispersion Models AERMOD and ISCST3 in the Houston Ship Channel Area
Sep 01, 2007; ... ABSTRACT 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 3, (ISCST3) model and the American Meteorological ...
A Combined Local and Nonlocal Closure Model for the Atmospheric Boundary Layer. Part I: Model Description and Testing
Sep 01, 2007; ... ABSTRACT 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 from the large range of turbulent scales that are ...
A Combined Local and Nonlocal Closure Model for the Atmospheric Boundary Layer. Part II: Application and Evaluation in a Mesoscale Meteorological Model
Sep 01, 2007; ... ABSTRACT 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 and field data in Part I. Herein, the incorporation ...
Sand Flux Simulations at a Small Scale over a Heterogeneous Mesquite Area of the Northern Chihuahuan Desert
Sep 01, 2007; ... ABSTRACT 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 through the open areas are correlated with sand flux and ...
Quantitative Ice Accretion Information from the Automated Surface Observing System
Sep 01, 2007; ... ABSTRACT 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 Weather Service (NWS), and by the development of ...
Sensitivity of a Mesoscale Model to Microphysical Parameterizations in the MAP SOP Events IOP2b and IOP8
Sep 01, 2007; ... ABSTRACT The sensitivity of a mesoscale model to different microphysical parameterizations is investigated for two events of precipitation in the Mediterranean region, that is, the Mesoscale Alpine Program (MAP) intensive observation periods (IOP) 2b (19-21 September 1999) and 8 (20-22 ...
Diagnosis of the Forcing and Structure of the Coastal Jet near Cape Mendocino Using In Situ Observations and Numerical Simulations
Sep 01, 2007; ... ABSTRACT Several flights were conducted by the University of Wyoming King Air near Cape Mendocino, California, during June 2004 to examine finescale features of the coastal low-level jet (CJ) that frequently forms during summer over the ocean off the West Coast of the United States. The ...
Year-Round Observation of Longwave Radiative Flux Divergence in Greenland
Sep 01, 2007; ... ABSTRACT 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, 38°30'W, 3203 m MSL is based on longwave radiation ...
A Robust Numerical Solution of the Stochastic Collection-Breakup Equation for Warm Rain
Sep 01, 2007; ... ABSTRACT 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) is discretized using the fixed-pivot scheme proposed by ...
