What are the responsibilities and job description for the Data Assimilation of Combined Lidar and Polarimeter Observations for the AOS Mission position at National Aeronautics and Space Administration (NASA)?
About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
This opportunity is closed to applicants who are Senior Fellows (5-years or more past PhD).
The forthcoming Atmosphere Observing System (AOS) mission aims to provide spaceborne observations to better understand aerosol, cloud, and precipitation processes and their interaction through a constellation of instruments in low earth orbit (aos.gsfc.nasa.gov) that includes a 3-channel Raman LIDAR and a 9-channel multi-angle polarimeter. The combined capabilities from these two instruments will provide unprecedented characterization of aerosol optical and physical properties, and their vertical distribution on a global scale. This project will focus on developing a strategy to best utilize this data in a global atmospheric data assimilation framework.
Activities that would be involved in this project include (but are not limited to):
- 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 for atmospheric data assimilation
- Utilize plume object tracking algorithms to characterize the source, transformation, and sinks of aerosols
