RISAn All-Weather Observational Operator for Radiance Data Assimilation with Mesoscale Forecast Models
Publisher: American Meteorological Society
Abstract: Assimilating satellite radiance data under all weather conditions remains an outstanding problem in numerical weather prediction. This study develops an observational operator for use in radiance assimilation under both ...
Analysis of 10.7-μm Brightness Temperatures of a Simulated Thunderstorm with Two-Moment Microphysics
Publisher: American Meteorological Society
Abstract: A cloud-resolving model was used in conjunction with a radiative transfer (RT) modeling system to study 10.7-?m brightness temperatures computed for a simulated thunderstorm. A two-moment microphysical scheme was used that ...
Comparison of WRF Model-Simulated and MODIS-Derived Cloud Data
Publisher: American Meteorological Society
Abstract: In this study, the ability of different combinations of bulk cloud microphysics and planetary boundary layer (PBL) parameterization schemes implemented in the Weather Research and Forecasting Model to realistically simulate ...
Computing the Atmospheric Absorption for the DMSP Operational Linescan System Infrared Channel
Publisher: American Meteorological Society
Abstract: An accurate and rapid means is presented for computing the atmospheric absorption for the infrared channel (10.2?12.7 ?m) on the Defense Meteorological Satellite Program operational linescan system (OLS) for use in remote ...
The GOES I–M Imagers: New Tools for Studying Microphysical Properties of Boundary Layer Stratiform Clouds
Publisher: American Meteorological Society
Abstract: This study reviews the capability of the advanced imagers on Geostationary Operational Environmental Satellites (GOES) I?M to provide quantitative information about bulk microphysical properties of low?level stratiform ...
A Three Parameter Representation of the Shape and Size Distributions of Hailstones—A Case Study
Publisher: American Meteorological Society
Abstract: The characteristics of shapes and sizes of a sample of 679 hailstones, collected on 22 June 1976 during a hailstorm at Grover, Colorado, were analyzed using a three-parameter formula developed by us previously. These ...
Evaluating the Accuracy of a High-Resolution Model Simulation through Comparison with MODIS Observations
Publisher: American Meteorological Society
Abstract: ynthetic infrared brightness temperatures (BTs) derived from a high-resolution Weather Research and Forecasting (WRF) model simulation over the contiguous United States are compared with Moderate Resolution Imaging ...
Validation of a Large-Scale Simulated Brightness Temperature Dataset Using SEVIRI Satellite Observations
Publisher: American Meteorological Society
Abstract: In this study, the accuracy of a simulated infrared brightness temperature dataset derived from a unique large-scale, high-resolution Weather Research and Forecasting (WRF) Model simulation is evaluated through a comparison ...
Uncertainties in Microwave Properties of Frozen Precipitation: Implications for Remote Sensing and Data Assimilation
Publisher: American Meteorological Society
Abstract: A combined active/passive modeling system that converts CloudSat observations to simulated microwave brightness temperatures (TB) is used to assess different ice particle models under precipitating conditions. Simulation ...
