Cloud Shading Retrieval and Assimilation in a Satellite-Model Coupled Mesoscale Analysis System
Publisher: American Meteorological Society
Abstract: A retrieval-assimilation method has been developed as a quantitative means to exploit the information in satellite imagery regarding shading of the ground by clouds, as applied to mesoscale weather analysis. Cloud radiative ...
Effects of Slope and Aspect Variations on Satellite Surface Temperature Retrievals and Mesoscale Analysis in Mountainous Terrain
Publisher: American Meteorological Society
Abstract: Surface temperature retrieval in mountainous areas is complicated by the high variability of temperatures that can occur within a single satellite field of view. Temperatures depend in part on slope orientation relative ...
Improved GOES Sounder Coverage of Cloud-Broken Data Fields
Publisher: American Meteorological Society
Abstract: 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 ...
Objective Analysis of Discontinuous Satellite-Derived Data Fields for Grid Point Interpolation
Publisher: American Meteorological Society
Abstract: In retrieval of atmospheric temperature and moisture soundings from satellite infrared radiance measurements the raw data commonly used consist of dense fields of radiances interrupted by data-free gaps. This note reports ...
Retrieval of Water Vapor Profiles via Principal Components: Options and Their Implications
Publisher: American Meteorological Society
Abstract: Principal components have been widely used in regression retrieval of atmospheric parameters, but when applied to water vapor concentrations their use entails special problems. We discuss two of these problem and present ...
Vertical Normal Modes of a Mesoscale Model Using a Scaled Height Coordinate
Publisher: American Meteorological Society
Abstract: Vertical modes were derived for a version of the Colorado State Regional Atmospheric Mesoscale Modeling System. We studied the impact of three options for dealing with the upper boundary of the model. The standard model ...
Mesoscale Analysis by Numerical Modeling Coupled with Sounding Retrieval from Satellites
Publisher: American Meteorological Society
Abstract: The development and evaluation of a system for time-continuous mesoscale analysis is presented, with a focus on retrieving water vapor concentrations and ground surface temperatures from VISSR Atmospheric Sounder (VAS) ...
Preconvective Mesoscale Analysis over Irregular Terrain with a Satellite-Model Coupled System
Publisher: American Meteorological Society
Abstract: Influences on the mesoscale distribution of summertime convective cloud development in the northeastern Colorado region are described using a new system for time-continuous mesoscale analysis. The analysis system is ...
Assimilation of Visible-Band Satellite Data for Mesoscale Forecasting in Cloudy Conditions
Publisher: American Meteorological Society
Abstract: Assimilation of satellite data can enhance the ability of a mesoscale modeling system to produce accurate short-term forecasts of clouds and precipitation, but only if there is a mechanism for the satellite-derived information ...
A Numerical Study of the Effect of GOES Sounder Cloud-Cleared Brightness Temperatures on the Prediction of Hurricane Felix
Publisher: American Meteorological Society
Abstract: The influence of Geostationary Operational Environmental Satellite (GOES) brightness temperature data on the numerical simulations of Hurricane Felix is investigated. Satellite data are included as an augmentation to a ...
