Trends in Attenuation Coefficients in Athens, Greece, from 1954 to 1991
(American Meteorological Society, 1995)Unsworth and Monteith's attenuation coefficient TUM was calculated from midday cloudless sky data in Athens, Greece, for the period 1954 to 1991. An interdependence between TUM and the Linke factor TL was found and is ... -
Detection of Warming Effects Due to Industrialization: An Accumulated Intervention Model with an Application in Pohang, Korea
(American Meteorological Society, 1995)Modifications of surface air temperature caused by anthropogenic impacts have received much attention recently because of the heightened interest in climatic change. When an industrial area is constructed, resulting in a ... -
Comparison of Lake-Breeze Model Simulations with Tracer Data
(American Meteorological Society, 1995)During the 1980s there were numerous occurrences of ozone exceedances of federal standards in the Lake Michigan area. An intensive field program was undertaken in order to gain insight into the dispersion patterns in the ... -
Variations of Wind Fluctuations Observed at 10 m over Flat Terrain under Unstable Atmospheric Conditions
(American Meteorological Society, 1995)Turbulence data collected at the 10-m level during convective conditions at a site located amid flat terrain in Alberta have been analyzed with respect to wind speed U and normalized static stability S?n. These two parameters ... -
The Dependence of Canyon Winds on Surface Cooling and External Forcing in Colorado's Front Range
(American Meteorological Society, 1995)The atmospheric katabatic flow in the foothills of the Front Range of the Rocky Mountains has been monitored by a network of towers and sodars for several years as part of the ASCOT program. The dependence of the outflow ... -
Intercomparison of Nocturnal Lower-Atmospheric Structure Observed with Lidar and Sodar Techniques at Pune, India
(American Meteorological Society, 1995)Coordinated experiments to study the nocturnal lower atmosphere were conducted on selected nights during April?August 1991 using an argon ion lidar and a Doppler sodar at the Indian Institute of Tropical Meteorology, Pune ... -
A Comparison of Columnar Water Vapor Retrievals Obtained with Near-IR Solar Radiometer and Microwave Radiometer Measurements
(American Meteorological Society, 1995)A simple two-channel solar radiometer and analysis technique have been developed for setting atmospheric water vapor via differential solar transmission measurements in and adjacent to the 940-nm water vapor absorption ... -
Effect of Wind Speed on Mixing Region Aerosol Concentrations at a Tropical Coastal Station
(American Meteorological Society, 1995)Altitude distribution of aerosols in the mixing region in a tropical coastal environment is studied using a bistatic continuous-wave lidar. It is found that aerosols remain fairly well mixed?their number density showing ... -
Nowcasting of Motion and Growth of Precipitation with Radar over a Complex Orography
(American Meteorological Society, 1995)Motion vectors of radar echo patterns can be obtained by applying a cross-correlation method (e.g., the TREC method) to radar data collected several minutes apart Here an extension of TREC, called COTREC, is presented. ... -
Microburst Rotation: Simulations and Observations
(American Meteorological Society, 1995)Microburst rotation can be determined by measuring the difference in azimuths between the maximum approaching and maximum receding velocity centers on a Doppler radar. Nonrotating microbursts would have these centers exactly ... -
The Use of Nested Models for Air Pollution Studies: An Application of the EURAD Model to a SANA Episode
(American Meteorological Society, 1995)A multiple-nesting version of the European Acid Deposition Model (EURAD) has been developed in order to increase the horizontal resolution in a region of enhanced pollution, namely the former German Democratic Republic. ... -
Backward-Time Lagrangian Stochastic Dispersion Models and Their Application to Estimate Gaseous Emissions
(American Meteorological Society, 1995)?Backward? Lagrangian stochastic models calculate an ensemble of fluid element (particle) trajectories that are distinguished by each passing through an observation point. As shown, they can be faster and more flexible in ... -
The Use of Cloud Reflectance Functions with Satellite Data for Surface Radiation Budget Estimation
(American Meteorological Society, 1995)The bidirectional reflectance distribution function (BRDF) of an overcast atmosphere above an ocean surface has been calculated as a function of wavelength using a discrete-ordinates radiative transfer model. This ... -
Determination of the Shortwave Anisotropic Function for Clear-Sky Desert Scenes from Meteosat Data
(American Meteorological Society, 1995)Determination of planetary albedo on the basis of satellite observations of reflected shortwave (SW) radiances requires taking into account the anisotropic (non-Lambertian) reflectance properties of the earth?atmosphere ... -
Climax Again?
(American Meteorological Society, 1995)A recent critique of the Climax cloud seeding experiments has raised many issues, which may cast doubt on the validity of those experiments? results. An attempt is made here to clarify the importance of these issues in the ... -

Responses of Warm-Based, Midwestern Cumulus Congestus to Dynamic Seeding Trials
(American Meteorological Society, 1995)Findings are reported from an analysis of AgI seeding effects on individual cumulus congestus clouds in the 1989 Illinois Exploratory Cloud Seeding Experiment. The experiment was designed around a dynamic seeding hypothesis. ... -
Exploratory Analysis of Seeding Effects on Rainfall: Illinois 1989
(American Meteorological Society, 1995)Radar-indicated rainfall characteristics from six experimental units randomly selected for AgI treatment were compared with those from six experimental units treated with sand during the summer of 1989 in an exploratory ... -
Estimates of Rainfall over the United Kingdom and Surrounding Seas from the SSM/I Using the Polarization Corrected Temperature Algorithm
(American Meteorological Society, 1995)The 85-GHz polarization corrected temperature (PCT85) algorithm, using the V85 and H85 channels of the SSM/I sensor, is evaluated for estimation of midlatitude rainfall. The algorithm ? parameter and rain/no-rain thresholds ...
