Modeling Ozone Formation and Transport in the Cascadia Region of the Pacific Northwest
(American Meteorological Society, 2000)The rapidly growing Cascadia region of the Pacific Northwest, consisting of western Washington, Oregon, and southwestern British Columbia, has experienced surface ozone concentrations that exceed federally mandated standards. ... -
Assimilation of NEXRAD-VAD Winds in Summertime Meteorological Simulations over the Northeastern United States
(American Meteorological Society, 2000)Next-Generation Radar (NEXRAD) velocity azimuth display (VAD) winds were available at 10 sites in the northeastern United States during intensive observing periods of the North American Research Strategy on Tropospheric ... -
Evaluating an Objective Wind Analysis Technique with a Long Record of Routinely Collected Data
(American Meteorological Society, 2000)An automated system has collected meteorological data hourly in the San Francisco Bay Area since October 1995. Data from sites operated by the National Weather Service, Federal Aviation Administration, U.S. Navy, U.S. Air ... -
Mesoscale Meteorological Structure of a High-Ozone Episode during the 1995 NARSTO-Northeast Study
(American Meteorological Society, 2000)Observations and numerical model fields were analyzed to study the meteorological structures contributing to high concentrations of lower-tropospheric ozone over the northeastern United States on 14?15 July 1995. It was ... -
Areal Rainfall Estimates Using Differential Phase
(American Meteorological Society, 2000)A radar polarimetric method for areal rainfall estimation is examined. In contrast to the polarimetric algorithm based on specific differential phase KDP, the proposed method does not require rain-rate estimation from KDP ... -
Simulation of Coherent Doppler Lidar Performance for Space-Based Platforms
(American Meteorological Society, 2000)The performance of coherent Doppler lidar velocity estimates for a space-based platform are produced using computer simulations of raw data and statistical descriptions of the resulting velocity estimates. The random spatial ... -
The Evolution of Photochemical Smog in the Metropolitan Area of Santiago de Chile
(American Meteorological Society, 2000)In November and December 1996 the PHOTOCHEMICAL CAMPAIGN took place in the Metropolitan Area of Santiago de Chile and covered a range of simultaneous measurements of meteorological parameters and air chemical compounds, ... -
Ozone Modeling Using Neural Networks
(American Meteorological Society, 2000)Ozone models for the city of Tulsa were developed using neural network modeling techniques. The neural models were developed using meteorological data from the Oklahoma Mesonet and ozone, nitric oxide, and nitrogen dioxide ... -
A Field-Coherence Technique for Meteorological Field-Program Design for Air Quality Studies. Part I: Description and Interpretation
(American Meteorological Society, 2000)This paper describes a new methodology developed to provide objective guidance for cost-effective siting of meteorological observations on the mesoscale for air quality applications. This field-coherence technique (FCT) ... -
Tenth Joint Conference on Applications of Air Pollution Meteorology with the Air and Waste Management Association

The Impact of the Diurnal Variation of Albedo on the Remote Sensing of the Daily Mean Albedo of Grassland
(American Meteorological Society, 2000)The correction of a land surface albedo estimate made at one solar zenith angle (SZA) from a polar-orbiting satellite to a standard SZA or to a daily mean albedo requires knowledge of the dependence of the albedo on SZA. ... -
Analyses of the Precipitation Pattern on the Alpine Region Using Different Cumulus Convection Parameterizations
(American Meteorological Society, 2000)The analysis of several precipitation events occurring during June 1990 in the Alpine region is performed using the Pennsylvania State University?National Center for Atmospheric Research Fifth-Generation Mesoscale Model, ... -
Cirrus Cloud Properties Derived from POLDER-1/ADEOS Polarized Radiances: First Validation Using a Ground-Based Lidar Network
(American Meteorological Society, 2000)Bidirectional polarized reflectances measured with the POLDER-1 instrument on board Advanced Earth Observing Satellite-1 have been used to infer cloud altitude and thermodynamical phase (ice/liquid) at a global scale. This ... -
Ground-Based Remote Sensing of Stratocumulus Properties during CLARA, 1996
(American Meteorological Society, 2000)A method is presented to obtain droplet concentration for water clouds from ground-based remote sensing observations. It relies on observations of cloud thickness, liquid water path, and optical extinction near the cloud ... -
Using a Genetic Algorithm to Tune a Bounded Weak Echo Region Detection Algorithm
(American Meteorological Society, 2000)Weather detection algorithms often rely on a simple rule base that is based on several features. Fuzzy logic can be used in the rule base, and the membership functions of the fuzzy sets can be tuned using a search or ... -
Optical Properties and Phase of Some Midlatitude, Midlevel Clouds in ECLIPS
(American Meteorological Society, 2000)Several cloud optical quantities were measured for the first time in midlevel, mixed-phase clouds. These included cloud infrared emittance and absorption coefficient (10?12 ?m), effective backscatter-to-extinction ratio, ... -
A Method of Evaluating Atmospheric Models Using Tracer Measurements
(American Meteorological Society, 2000)The authors have developed a method that uses tracer measurements as the basis for comparing and evaluating wind fields. An important advantage of the method is that the wind fields are evaluated from the tracer measurements ... -
Wintertime Ozone Fluxes and Profiles above a Subalpine Spruce–Fir Forest
(American Meteorological Society, 2000)High rural concentrations of ozone (O3) are thought to be stratospheric in origin, advected from upwind urban sources, or photochemically generated locally by natural trace gas emissions. Ozone is known to be transported ... -
Dynamic Aspects of the Impact of the Use of Perfect Climate Forecasts in the Corn Belt Region
(American Meteorological Society, 2000)A general equilibrium model is linked to a decision model to determine the impact of perfect growing season forecasts for corn produced in the Corn Belt region over a 10-yr period. Five different timing scenarios are ... -
