Session A103: The Underapprecipated Aerosol Coarse Mode: Impacts on Climate and Biogeochemistry

 

Session ID#: 29190

Session Description: The coarse mode tends to be ignored because it is difficult to measure, and the perception that it does not exert a large effect on aerosol forcing or chemistry. However, coarse mode aerosols can have substantial impact on ice nuclei concentrations, on shortwave and longwave radiative forcings, and when deposited change the biogeochemistry and impact on the carbon cycle. There is a need to synthesize the current state of knowledge about coarse mode aerosol, including the sources, physical and chemical characteristics, size distributions, optical properties, contribution to ice nucleation, atmospheric processing, and fate, to better quantify their role in biogeochemical cycles and the climate system. This session is being developed to encourage the presentation of work that addresses these aspects of coarse mode aerosol in measurements and models to encourage synthesis of our understanding. Individual observational studies at specific locations, cross-scales studies, and global modeling synthesis studies are encouraged.

Session A059: Light Scattering and Radiative Transfer: Basic Research and Applications

https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session22776

 

Session ID#: 22776

Session Description: 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 P033. Polarimetry as an invaluable tool to study the Solar System and beyond

https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session22335

 

Session ID#: 22335

Session Description: Polarimetry is a powerful observing tool and modeling technique, providing information about astronomical objects that cannot be obtained by traditional photometric/spectroscopic observations. Applications include characterization of solar system objects (Sun, Earth, planetary atmospheres, aurorae, comets, asteroids, planetary satellites/ring systems, dust, etc.) to the detection of exoplanets and identification of biological markers in search of habitability. Innovative developments in vector radiative transfer theory ; laboratory measurements, and the increasing significance of non-sphericity effects on retrieval efforts showcase the importance of polarimetric exploration of the solar system and other planetary systems. This session is open to papers about observations of solar system bodies, theoretical or experimental investigations, instrumental developments ground-based facilities or onboard future space missions.
