Education and career Lin earned a Bachelor of Science (B.S.) from National Taiwan University. He also holds a master's degree in aeronautical engineering from the University of Oklahoma and a doctorate in geophysical fluid dynamics from Princeton University.NASA After a postdoctoral position at the Center for Analysis and Prediction of Storms at the University of Oklahoma he became a scientist at the Laboratory for Atmospheres at NASA's Goddard Space Flight Center, where he developed the Lin and Rood advection scheme,Lin, S. and R.B.

Lin joined GFDL in 2003. He has since led development of FV3, the extension of FV onto a cubed-sphere grid,Putman, W.M. and Lin, S.J., 2007. Finite-volume transport on various cubed-sphere grids. Journal of Computational Physics, 227(1), pp.55-78. and a relaxation of the hydrostatic assumption to allow explicit simulation of vertical accelerations.

The latter is a prototype for the Next-Generation Global Prediction System (NGGPS),Next Generation Global Prediction System (NGGPS) for which FV3 was selected after a two-year evaluation period. It was found that FV3 produced more accurate forecasts with better numerical stability compared to competing dynamical cores without sacrificing realism, efficiency, or effective resolution.Next Generation Global Prediction System (NGGPS): Phase 2 Atmospheric Dynamic Core EvaluationNext Generation Global Prediction System (NGGPS): Phase 2 Atmospheric Dynamic Core Evaluation Briefing The first operational NGGPS model, an FV3-based Global Forecast System,FV3GFS OFFICIAL EVALUATION became operational on 12 June 2019.
In 2018 Lin was named a fellow of the American Meteorological Society.American Meteorological Society: 2018 Awards and Honors Recipients
