Curriculum Vitae:

Keeyoon Sung

  • B.A. in English Education, Seoul National University, Seoul, Korea (1990)
  • B.Sc. in Astron. Space Sci., Chungnam Nat’l Univ.  S. Korea (1996)
  • Ph.D. in Atmospheric Sciences, ITPA/MSRC, SUNY at Stony Brook, NY (2003)

Research Interests
  • Laboratory study on molecular spectroscopy of atmospheric molecules
  • High-resolution high-precision spectroscopy of CO, CO2, CH4, NH3, and C2H6.
  • Temp.-dependent cross sections for hydrocarbons (C3H8, C6H6, C3H6, etc)
  • Development and validation of spectral line shape models to support the OCO-2 mission
  • Atmospheric remote sensing using a MK-IV (ground-based and air-borne FT-IR)
  • Mass spectrum analysis for isotopic abundance characterization using IRMS


High Resolution Infrared Spectroscopy Icon High Resolution Infrared Spectroscopy
This effort supports atmospheric remote sensing of the Earth, our Solar System (planets, moons and comets) and some astronomical bodies (such as stars and their planets, brown dwarfs).

Atmospheric observations with MK-IV Icon Atmospheric observations with MK-IV
Mark IV interferometer team uses a mid-infrared Fourier transform interferometer to measure the atmosphere using the Sun as a source.

OCO-2 - Orbiting Carbon Observatory Icon OCO-2 - Orbiting Carbon Observatory
The Orbiting Carbon Observatory-2 (OCO-2) is a mission designed to make precise, time-dependent global measurements of atmospheric carbon dioxide (CO2) from an Earth orbiting satellite.
