Postdoctoral Scholar Position – Innovative Ocean Modeling for Satellite Ocean Salinity / Jet Propulsion Laboratory (JPL), California Institute of Technology (Caltech). The California Institute of Technology Postdoctoral Scholars Program at JPL invites applications for a postdoctoral scholar position at the Ocean Circulation Group. The research will focus on studying ocean salinity and freshwater flux. Analyzing satellite data (e.g., ocean surface salinity, GRACE ocean‑bottom‑pressure, and altimetry sea‑level) and model results is necessary.

The modeling effort aims to improve understanding of near‑surface salinity stratification and river runoffs. Specific scientific focus will depend upon the qualifications and interests of the incumbent.

Dr. Y. Tony Song, Research Scientist in JPL's Earth Science Section, will serve as the JPL postdoctoral advisor to the selected candidate. The appointee will be guided by the JPL advisor to ensure that the research work results in publications in the open literature.

• Study ocean salinity and freshwater flux using satellite data and models.
• Analyze satellite data such as ocean surface salinity, GRACE ocean‑bottom‑pressure, and altimetry sea‑level.
• Improve the understanding of near‑surface salinity stratification and river runoffs through modeling.

• Recent Ph.D. in oceanography, computational fluid dynamics, or a related field.
• Skills in Unix/Linux, Matlab, and parallel computing.
• Prior experience with community user models, particularly ROMS, is a plus.
• Proficiency in written and spoken English.
