RISModeling Cirrus Clouds. Part II: Treatment of Radiative Properties
Publisher: American Meteorological Society
Abstract: A new radiation scheme, suitable for two-stream radiation transfer models, was developed for cirrus clouds. Analytical expressions were derived for the extinction and absorption coefficients and the asymmetry parameter. ...
Single Scattering Properties of Atmospheric Ice Crystals
Publisher: American Meteorological Society
Abstract: Simulations of scattering and polarization properties for randomly oriented polyhedral ice crystals are presented based on the geometric optics and the far-field diffraction approximation. Particle shapes range from various ...
Retrieval of Surface Solar Radiation Budget under Ice Cloud Sky: Uncertainty Analysis and Parameterization
Publisher: American Meteorological Society
Abstract: This study investigates and accounts for the influence of various ice cloud parameters on the retrieval of the surface solar radiation budget (SSRB) from reflected flux at the top of the atmosphere (TOA). The optical ...
Combining the Perspective of Satellite- and Ground-Based Observations to Analyze Cloud Frontal Systems
Publisher: American Meteorological Society
Abstract: method is presented to analyze the cloud life cycle of frontal systems passing over European supersites. It combines information on the vertical profiles of cloud properties derived from ground-based observations with cloud ...
Measured and Parameterized Energy Fluxes Estimated for Atlantic Transects of R/V Polarstern
Publisher: American Meteorological Society
Abstract: ensible and latent heat fluxes were estimated from turbulence measurements gathered during several Atlantic Ocean transects of the research vessel (R/V) Polarstern. The inertial dissipation method was used to analyze the ...
A New Parameterization of Single Scattering Solar Radiative Properties for Tropical Anvils Using Observed Ice Crystal Size and Shape Distributions
Publisher: American Meteorological Society
Abstract: Parameterizations of single scattering properties currently used in cloud resolving and general circulation models are somewhat limited in that they typically assume the presence of single particle habits, do not adequately ...
A Standardized Atmospheric Measurement Data Archive for Distributed Cloud and Precipitation Process-Oriented Observations in Central Europe
Publisher: American Meteorological Society
Abstract: AbstractCentral Europe has a vital and extensive meteorological research community comprising national weather services, universities, and research organizations and institutes. Nearly all of them are involved in the open ...
The Arctic Cloud Puzzle: Using ACLOUD/PASCAL Multiplatform Observations to Unravel the Role of Clouds and Aerosol Particles in Arctic Amplification
Publisher: American Meteorological Society
Abstract: AbstractClouds play an important role in Arctic amplification. This term represents the recently observed enhanced warming of the Arctic relative to the global increase of near-surface air temperature. However, there are ...
THE I3RC: Bringing Together the Most Advanced Radiative Transfer Tools for Cloudy Atmospheres
Publisher: American Meteorological Society
Abstract: The interaction of clouds with solar and terrestrial radiation is one of the most important topics of climate research. In recent years it has been recognized that only a full three-dimensional (3D) treatment of this ...
