From Model-Based Parameterizations to Lookup Tables: An EOF Approach
Publisher: American Meteorological Society
Abstract: The goal of this study is to transform the Harrington radiation parameterization into a transfer scheme or lookup table, which provides essentially the same output (heating rate profile and short- and longwave fluxes at ...
Multiresolution Analysis of Radiative Transfer through Inhomogeneous Media. Part II: Validation and New Insights
Publisher: American Meteorological Society
Abstract: The multiresolution radiative transfer equations of Part I of this paper are solved numerically for the case of inhomogeneous model clouds using Meyer?s basis functions. After analyzing the properties of Meyer?s connection ...
Parameterization of Atmospheric Radiative Transfer. Part I: Validity of Simple Models
Publisher: American Meteorological Society
Abstract: This paper outlines a radiation parameterization method for deriving broadband fluxes that is currently being implemented in a number of global and regional atmospheric models. The rationale for the use of the 2-stream ...
Parameterization of Atmospheric Radiative Transfer. Part II: Selection Rules
Publisher: American Meteorological Society
Abstract: This paper describes simple, computationally efficient methods of calculating 2-stream broadband fluxes and heating rates in the shortwave and longwave for multilayered media. The method, herein referred to as selection ...
Effects of Tunable Data Compression on Geophysical Products Retrieved from Surface Radar Observations with Applications to Spaceborne Meteorological Radars
Publisher: American Meteorological Society
Abstract: his paper presents results and analyses of applying an international space data compression standard to weather radar measurements that can easily span eight orders of magnitude and typically require a large storage capacity ...
An Assessment of the Parameterization of Subgrid-Scale Cloud Effects on Radiative Transfer. Part I: Vertical Overlap
Publisher: American Meteorological Society
Abstract: Different approaches for parameterizing the effects of vertical variability of cloudiness on radiative transfer are assessed using a database constructed from observations derived from lidar and millimeter cloud radar data ...
An Assessment of the Parameterization of Subgrid-Scale Cloud Effects on Radiative Transfer. Part II: Horizontal Inhomogeneity
Publisher: American Meteorological Society
Abstract: The role of horizontal inhomogeneity in radiative transfer through cloud fields is investigated within the context of the two-stream approximation. Spatial correlations between cloud optical properties and the radiance ...
Objective Assessment of the Information Content of Visible and Infrared Radiance Measurements for Cloud Microphysical Property Retrievals over the Global Oceans. Part II: Ice Clouds
Publisher: American Meteorological Society
Abstract: Cirrus clouds play an important yet poorly determined role in the earth?s climate system and its various feedback mechanisms. As such, a significant amount of work has been accomplished both in understanding the physics ...
Objective Assessment of the Information Content of Visible and Infrared Radiance Measurements for Cloud Microphysical Property Retrievals over the Global Oceans. Part I: Liquid Clouds
Publisher: American Meteorological Society
Abstract: The importance of accurately representing the role of clouds in climate change studies has become increasingly apparent in recent years, leading to a substantial increase in the number of satellite sensors and associated ...
Spectral Reflectance and Atmospheric Energetics in Cirrus-like Clouds. Part II: Applications of a Fourier-Riccati Approach to Radiative Transfer
Publisher: American Meteorological Society
Abstract: One of the major sources of uncertainty in climate studies is the detection of cirrus clouds and characterization of their radiative properties. Combinations of water vapor absorption channels (e.g., 1.38 µm), ice-water ...
