Session A088 - Light Scattering and Radiative Transfer: Basic Research and Applications 

Light scattering and radiative transfer are two important branches of atmospheric physics essential to the implementation of advanced remote sensing techniques and the investigation of the radiative forcings caused by various atmospheric constituents (clouds and aerosols, in particular). This session provides a forum for the presentation of recent advances in electromagnetic scattering, such as the scattering properties of nonspherical aerosol particles and ice crystals, 3-D radiative transfer, vector radiative transfer simulations, fast radiative transfer models for the interpretation of hyperspectral measurements, and the use of fundamental light scattering and radiative transfer theories in active and passive remote sensing applications. 



Session A031 - Atmospheric Radiative Transfer through Clouds and Precipitation: Applications to Remote Sensing and Data Assimilation

Modeling atmospheric radiative transfer through clouds and precipitation is highly complex and computationally expensive, but the community is finally at the intersection where the model complexity and computational resources are roughly comparable. In atmospheric data assimilation, operational centers are focusing on assimilating radiances impacted by clouds and precipitation, and this represents an opportunity for researchers to share knowledge and coordinate efforts where appropriate. There are many factors that contribute to this complexity: (1) the physical description of the atmosphere, from thermodynamics, dynamics, hydrometeor properties, and the scales of observation / simulation; (2) The microphysical assumptions that are employed in various models; (3) the radiative transfer model itself, with a wide variety of approximations and ranges of applicability; (4) and the ultimate goals of using atmospheric RT in applications from remote sensing and data assimilation. Given this broad scope, this session seeks contributions that represent the state-of-the-art approaches to efficient and accurate simulation of sensor-based radiative transfer in cloudy / precipitating scenes. A particular emphasis is placed on simulating satellite-based observations, such as are used in atmospheric remote sensing and data assimilation. Ground-based simulations are also welcome, particularly those that are used in a retrieval or assimilation framework. Presentations should aim at describing the technical aspects of the radiative transfer model, the implementation, ranges of applicability, and preferably provide some end-to-end examples of how the RT models are used for cloudy/precipitating scenes in their respective frameworks.
