Effects of Dry Deposition on Near-Surface Concentrations of SO2 during Medium-Range Transport
(American Meteorological Society, 1998)The method for estimating dry deposition velocity using local routine surface measurements with some empirical constants used in the Regional Acid Deposition Model is developed and implemented to the Lagrangian particle ... -
Ice Loads on a Lattice Tower Estimated by Weather Station Data
(American Meteorological Society, 1998)Atmospheric ice loads are a major design criterion of tall structures in cold regions. In this paper the possibility to derive the design ice loads using analysis of meteorological observations made routinely at a weather ... -
Wind and Temperature Profiles in the Radix Layer: The Bottom Fifth of the Convective Boundary Layer
(American Meteorological Society, 1998)In the middle of the convective atmospheric boundary layer is often a deep layer of vertically uniform wind speed (MUL), wind direction, and potential temperature (?UL). A radix layer is identified as the whole region below ... -
Development of Temperature Patterns during Clear Nights
(American Meteorological Society, 1998)This paper examines nocturnal air temperature structure development in complex terrain. Clear nights were studied in order to compare the cooling rate in different topographical areas with a variety of land cover. It was ... -
Improved GOES Sounder Coverage of Cloud-Broken Data Fields
(American Meteorological Society, 1998)Geostationary satellite sounder radiances have typically been averaged over several individual fields of view before the radiances are used for retrieving thermodynamic profiles or for assimilation in weather prediction ... -
Simulating Surface Energy Fluxes and Radiometric Surface Temperatures for Two Arid Vegetation Communities Using the SHAW Model
(American Meteorological Society, 1998)While land?atmosphere transfer models have been pursued for over 30 years, Soil?Vegetation?Atmosphere?Transfer (SVAT) models are gaining attention only recently as the need to better represent the interaction between the ... -
Method for Estimation of Surface Roughness and Similarity Function of Wind Speed Vertical Profile
(American Meteorological Society, 1998)This study is aimed at identifying and refining a method suitable to estimate the surface roughness length (z0) and the universal similarity function of the wind speed profile (?M) based on ultrasonic anemometer measurements ... -
A New Method for Estimating Roughness Parameters and Evaluating the Quality of Observations
(American Meteorological Society, 1998)A new method for estimating the roughness parameters (displacement height d, momentum roughness length zo, and friction velocity u?), under adiabatic conditions, is introduced in this paper. The goals of this method are ... -
Predicting Total Ozone Based on GTS Data: Applications for South American High-Latitude Populations
(American Meteorological Society, 1998)A regular occurrence during the 1990s has been the excursion of the edge of the springtime Antarctic ozone hole over the southernmost region of the South American continent. Given the essential role of atmospheric ozone ... -
Turbidity Determination from Broadband Irradiance Measurements: A Detailed Multicoefficient Approach
(American Meteorological Society, 1998)A physically modeled method is presented to obtain accurate turbidity determinations from broadband direct irradiance measurements. The method uses parameterizations of various extinction processes affecting the transfer ... -
Daytime Photochemical Pollutant Transport over a Tributary Valley Lake in Southwestern British Columbia
(American Meteorological Society, 1998)Tethersonde, lidar, aircraft, and surface chemistry measurements from an intensive field campaign (Pacific?93) in the Lower Fraser Valley (LFV) demonstrate the daytime advection of pollutants into a lake-filled valley ... -
A Simple Method for Estimating the Latent Heat Flux over Grass from Radiative Bowen Ratio
(American Meteorological Society, 1998)The evaluation of crop evapotranspiration from infrared temperature is usually calculated as the residual component of the surface energy balance. This method has given good results over a full grass canopy cover with ... -
Cloud-Top Heights from GOES-8 and GOES-9 Stereoscopic Imagery
(American Meteorological Society, 1998)Operational satellite data from GOES-8 and GOES-9 were used to make stereoscopic measurements of cloud heights during the National Aeronautics and Space Administration?s Subsonic Aircraft: Contrail and Cloud Effects Special ... -
The Application of the Revised Algorithm for the Prediction of the Formation of Exhaust Condensation Trails by Jet Aircraft
(American Meteorological Society, 1998)Application is made of the Hanson and Hanson algorithm for contrail production to predict the presence of a contrail (condensation trail) by jet aircraft. Two databases are utilized, one based on the contiguous 48 states ... -
Observations in Nonurban Heat Islands
(American Meteorological Society, 1998)The urban heat island is a well-known and well-described temperature anomaly, but other types of heat islands are also infrequently reported. A 10 km ? 30 km data field containing more than 100 individual winter morning ... -
A Comparison between Different Methods to Estimate the Lateral Dispersion Parameter under Convective Conditions
(American Meteorological Society, 1998)A new formulation for the lateral dispersion parameter is presented. The model is valid for unstable atmospheric conditions and based on the turbulent kinetic energy spectra and Taylor diffusion theory. It has been tested ... -
Land Surface Energy and Moisture Fluxes: Comparing Three Models
(American Meteorological Society, 1998)Three different land surface schemes that are designed for use in atmospheric general circulation models are compared. They were run in offline mode with identical atmospheric forcing values that were observed at Cabauw. ... -
Estimation of the Entrainment Zone Depth in a Shallow Convective Boundary Layer from Sodar Data
(American Meteorological Society, 1998)This paper describes several methods for estimating the depth of the entrainment zone (?h) at the top of the daytime convective boundary layer (CBL) from sodar data. Both averaged profiles of sound backscatter intensity ... -
On Combining Instruments
(American Meteorological Society, 1998)Suppose two instruments I0 and I1 measure the same quantity with the same resolution, where it is known that I0 is more reliable. The second, I1, is assumed a distortion of I0 in some sense. A statistical method is outlined ... -
