An 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 ...
The Successive-Order-of-Interaction Radiative Transfer Model. Part I: Model Development
Publisher: American Meteorological Society
Abstract: This study, the first part of a two-part series, develops the method of ?successive orders of interaction? (SOI) for a computationally efficient and accurate solution for radiative transfer in the microwave spectral region. ...
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 ...
Fast Computation of Microwave Radiances for Data Assimilation Using the “Successive Order of Scattering” Method
Publisher: American Meteorological Society
Abstract: Fast and accurate radiative transfer (RT) models are crucial in making use of microwave satellite data feasible under all weather conditions in numerical weather prediction (NWP) data assimilation. A multistream ?successive ...
