Radiative Transfer Models for Aerosol Remote Sensing Signals with Polarization

This project is an inter-comparison task that began when the Jet Propulsion Laboratory (JPL) began moving into polarized (vector) radiative transfer. A number of codes existed and since then more have been developed. NASA has been developing new instrumentation to study aerosols from high-altitude aircraft, and eventually from satellites. The task at hand is to compare a total of eight physics-based computer models, contributed from researchers around the globe, to make sure the codes agree with one another across a set of cases that are representative of aerosols in the real world. Different atmospheric stratifications and underlying surfaces are also considered that cover a broad range of possible observation scenarios.

Performance metrics will be implemented to compare the models with one another efficiently. This project will present the performance of these different models in a way that is understandable, clear, and will help the lead team decide which models are to be invested in while seeking the best workhorse for the new aerosol retrieval algorithms to be used for processing data from future instrumentation.
