The Operational Calibration of Images Taken in the Visible Channel of the Meteosat Series of Satellites
(American Meteorological Society, 2002)A method and its implementation are presented for the automatic calibration of the images taken in the visible channel of the Meteosat series of satellites. The method performs on a daily basis and is based on a statistical ... -
A Homogenized Historical Temperature Extreme Dataset for the United States
(American Meteorological Society, 2002)A subset of stations from the daily U.S. Historical Climatology Network (HCN) is used as a basis for a historical database of temperature extreme occurrence in the United States. The dataset focuses on daily temperature ... -
Rapid Calibration of Operational and Research Meteorological Satellite Imagers. Part II: Comparison of Infrared Channels
(American Meteorological Society, 2002)To establish a more reliable reference instrument for calibration normalization, this paper examines the differences between the various thermal infrared imager channels on a set of research and operational satellites. ... -
Rapid Calibration of Operational and Research Meteorological Satellite Imagers. Part I: Evaluation of Research Satellite Visible Channels as References
(American Meteorological Society, 2002)Operational meteorological satellites generally lack reliable onboard calibration systems for solar-imaging channels. Current methods for calibrating these channels and for normalizing similar channels on contemporaneous ... -
Horizontal Turbulent Fluxes of Sensible Heat and Horizontal Homogeneity in Micrometeorological Experiments
(American Meteorological Society, 2002)Acoustic travel time measurements are used to investigate the spatial and temporal variability of air temperature and wind fields in the atmospheric surface layer. The observational system consists of several sound sources ... -
A New Concept for Estimation of Turbulent Parameter Profiles in the ABL Using Sodar Data
(American Meteorological Society, 2002)Many classes of dispersion models used for air pollution nowcasting and forecasting require vertical profiles of turbulent parameters as input. A method of estimation of such profiles in the ABL using sodar data is proposed. ... -
Acoustic Tomography as a Remote Sensing Method to Investigate the Near-Surface Atmospheric Boundary Layer in Comparison with In Situ Measurements
(American Meteorological Society, 2002)The acoustic tomography method is applied in the atmospheric surface layer to observe near-surface temperature fields. Important advantages of this technique are the remote sensing capacity and the possibility of directly ... -
Use of an Ultrasonic Sodar to Sense Raindrop Size Distributions
(American Meteorological Society, 2002)The design of a sodar that uses ultrasound to remotely sense drop size distributions in rainfall is described. The Doppler shift is proportional to a drop's terminal velocity and gives a measure of the drop diameter, whereas ... -
DIAS: Differential Absorption of Sound to Obtain Temperature Profiles from Multifrequency Sodar
(American Meteorological Society, 2002)The differential absorption of sound (DIAS) depends on frequency, temperature, and humidity in a known fashion. By obtaining turbulent reflections at two or more frequencies from the same target air mass, it is possible ... -
Radio Acoustic Sounding in Urban Meteorological Observations
(American Meteorological Society, 2002)Meteorological observations are carried out using a mobile Radio Acoustic Sounding System (RASS), a radiosonde system, and ground-based meteorological measurement systems in order to understand urban meteorological conditions. ... -
Response Characteristics of the U.W. Sonic Anemometer
(American Meteorological Society, 1986)A new sonic anemometer, called the U.W. sonic anemometer, has been designed to minimize the flow distortion due to the transducer wakes. We present a general analytical model for calculating the effect of these transducer ... -
Experimental Study of the Vertical Structure of the Lower Troposphere over a SmallGreek Island in the Aegean Sea
(American Meteorological Society, 2002)An experimental campaign was carried out on a small Greek island that is characterized by complex terrain; its aim was to study the local characteristics of the vertical structure of the atmospheric boundary layer (ABL). ... -
A Doppler Sodar Case Study of Top-Down Convection and Convective Dissipation of Stratus
(American Meteorological Society, 2002)Stratus dissipation over the Swiss Plateau has long been a forecasting problem. A case study of stratus structure and development was conducted during the winter of 1997/98. Measurements were performed with the monostatic ... -
Expressions of Sensible Heat Flux Based on a Dimensional Analysis
(American Meteorological Society, 2002)Based on a dimensional analysis, relationships between the temperature structure coefficient C2T, the variance of vertical wind speed σ2w or the velocity structure coefficient C2V, and the sensible heat flux in the boundary ... -
Long-Term Sodar Observations in Moscow and a New Approach to Potential Mixing Determination by Radiosonde Data
(American Meteorological Society, 2002)The experimental data about thermal stratification of a low layer of atmosphere, received by the sodar sounding and direct measurements simultaneously, are summarized and discussed. The conclusion was made that sodar records ... -
