Primitive Analysis of the Ship Tracking Problem
(American Meteorological Society, 2000)Satellite images reveal tracks of enhanced solar reflectivity in low-level stratus clouds over the ocean that are known to be produced by the aerosols emitted from diesel-powered ships. The question arises: Can we track a ... -
Cloud Detection Using Meteosat Imagery and Numerical Weather Prediction Model Data
(American Meteorological Society, 2000)The cloud detection algorithm of the Royal Netherlands Meteorological Institute (KNMI) Meteosat Cloud Detection and Characterization KNMI (Metclock) scheme is introduced. The algorithm analyzes the Meteosat infrared and ... -
Microwave Brightness Temperatures from Tilted Convective Systems
(American Meteorological Society, 2000)Aircraft and ground-based radar data from the Tropical Ocean and Global Atmosphere Coupled Ocean?Atmosphere Response Experiment show that convective systems are not always vertical. Instead, many are tilted from vertical. ... -
Diagnostic of Supercooled Clouds from Single-Doppler Observations in Regions of Radar-Detectable Snow
(American Meteorological Society, 2000)Liquid water is produced in the updraft regions of subfreezing clouds when the generation of vapor excess over the water saturation value exceeds the vapor depletion through the depositional growth of the solid particles. ... -
The Retrieval of Effective Particle Radius and Liquid Water Path of Low-Level Marine Clouds from NOAA AVHRR Data
(American Meteorological Society, 2000)An algorithm was developed to retrieve both the optical thickness and the effective particle radius of low-level marine clouds simultaneously from National Oceanic and Atmospheric Administration Advanced Very High Resolution ... -
Practical Aspects of Radar Rainfall Estimation Using Specific Differential Propagation Phase
(American Meteorological Society, 2000)Rainfall estimation using specific differential phase (KDP) involves estimation of KDP over a propagation path. The choice of pathlength plays an important role in the performance of rainfall algorithms using KDP. The ... -
Coupled Atmosphere–Biophysics–Hydrology Models for Environmental Modeling
(American Meteorological Society, 2000)The formulation and implementation of LEAF-2, the Land Ecosystem?Atmosphere Feedback model, which comprises the representation of land?surface processes in the Regional Atmospheric Modeling System (RAMS), is described. ... -
Estimation of Ultraviolet-B Irradiance under Variable Cloud Conditions
(American Meteorological Society, 2000)Methods to estimate the irradiance of ultraviolet-B (UVB; 280?320 nm) radiation are needed to assess biological effects of changes in atmospheric composition. Measurements of the spatial distribution of sky cloud cover, ... -
Simultaneous Retrieval of Diurnal to Seasonal Surface Temperatures and Emissivities over SGP ARM–CART Site Using GOES Split Window
(American Meteorological Society, 2000)GOES-8 thermal infrared split window measurements have been used with a simultaneous land surface temperature (LST)?spectral emissivity retrieval algorithm to examine the potential of a combined retrieval methodology cast ... -
Solar Spectral Irradiance under Clear Skies around a Major Metropolitan Area
(American Meteorological Society, 2000)This paper investigates the influence of gaseous pollutants and aerosol on the spectral composition of various segments of the solar spectrum in cloudless conditions. This investigation is done by using data of the spectral ... -
Determination of Shortwave Earth Reflectances from Visible Radiance Measurements: Error Estimate Using ScaRaB Data
(American Meteorological Society, 2000)The error resulting from the use of a visible channel to estimate shortwave (SW) (0.2?4 ?m) fluxes reflected by the earth is analyzed. First, the authors compute regression coefficients between visible (0.55?0.65 ?m) and ... -
Chemical Heterogeneity across Cloud Droplet Size Spectra in Continental and Marine Air Masses
(American Meteorological Society, 2000)Variations in the chemical composition of cloud droplets of different sizes are predicted in models. Measurements made in natural clouds to verify this prediction are extremely limited, however. During the spring of 1995 ... -
Quantification of Path-Integrated Attenuation for X- and C-Band Weather Radar Systems Operating in Mediterranean Heavy Rainfall
(American Meteorological Society, 2000)The aim of the current study is to quantify attenuation effects that X- and C-band weather radar systems may experience in heavy rainfall. Part of this information can be obtained from power-law relationships between the ... -
A New Method for Determining the Ångström Turbidity Coefficient from Broadband Filter Measurements
(American Meteorological Society, 2000)In this work, a new method for determining Ångström turbidity coefficients is presented. This method is based on broadband filter irradiance measurements. By combining measurements obtained with different filters it is ... -
Ozone Destruction in Continental Stratus Clouds: An Aircraft Case Study
(American Meteorological Society, 2000)Apparent depletion of ozone in a cold (?0°C), continental stratus cloud system was observed during in situ data collection on 30 April 1994 at the Department of Energy Clouds and Radiation Test Bed site in northern Oklahoma. ... -
Nocturnal Air Temperature Variations between Forest and Open Areas
