Data Assimilation of Combined Lidar and Polarimeter Observations for the AOS Mission

About the role

The Data Assimilation of Combined Lidar and Polarimeter Observations for the AOS Mission opportunity is part of the NASA Postdoctoral Program (NPP), which offers one- to three-year fellowships to scientists engaged in NASA research projects.

Description

This project focuses on developing a strategy to best utilize combined Raman LIDAR and multi-angle polarimeter observations in a global atmospheric data assimilation framework. Activities include:

• Develop algorithms to characterize aerosol speciation from LIDAR fluorescence signals
• Develop machine learning emulators to represent forward operators for polarimeter-only and combined polarimeter and lidar observations
• Utilize plume object tracking algorithms to characterize the source, transformation, and sinks of aerosols
