Session papers are solicited for subjects, key issues, and emerging applications that are of interest but not limited to:

1. The use of radiation measurements to improve weather/environment & climate forecasting.
- Implementation, validation and comparison of radiative transfer parameterization within weather/environment and climate models.
- Technique and results of assimilating radiation quantities into weather/environment forecast and climate models.

- The prediction and validation of radiation quantities from weather and climate models.
- Verification of model simulations of radiation and other meteorological and climate variables.
- Scaling of sub-grid radiative processes into large scale climate models (e.g. local aerosol sources, open leads in Arctic and Antarctic waters).

2. Radiative processes in weather/environment and climate, and their consequences (e.g., cloud-climate interactions, aerosol-chemistry-climate interactions, atmosphere-ocean interactions)
- Climate variations and changes due to natural and anthropogenic radiative forcings; climate feedbacks and sensitivity, global and regional changes, impacts on the hydrologic cycle, and comparisons of model simulations with observations.
- Diagnostic analyses of the weather and climate system utilizing model simulations and observations (e.g., space-borne and ground-based) on a variety of spatial and temporal scales.

3. Global and regional radiation climatologies
- Detection and characterization of climate trends/changes.
- Regional trends/changes in radiation regimes and their environmental impacts.
- Climate data record management, access, quality control, and stewardship.

4. Other topics such as
- Design, development, and implementation of future weather/environment/climate sensor systems.
- National and international weather/environment/climate research program and initiative
- Other general climate studies that are related to climate variability and changes, such as those on climate analysis method, data quality, new data sets, observation systems, etc.

5. Other key issues and emerging applications such as
- Improvements in weather/environment forecasts as a consequence of improved parameterization of radiative process guided by theoretical knowledge and observations.
- Variations in radiation, hydrologic and other climate variables on timescales ranging from seasonal to interannual, and to interdecadal, with implications for climate sensitivity.
