  • Brief Bio

    Dr. Min-Jeong Kim joined NASA Goddard's Global Modeling and Assimilation Office (GMAO) in August 2013 and she has been developing the all-sky(clear+cloudy+precipitating sky) radiance data assimilation system in the Goddard Earth Observing System (GEOS-5) Model. Using her uniquely combined experiences in passive/active microwave remote sensing of precipitation, numerical prediction modeling and data assimilation system developjments, she is currently building various components to utilize GPM Microwave Imager (GMI) radiance data in GEOS-5 Atmospheric Data Assimilation System (ADAS) to improve global cloud and precipitation analyses and forecasts.

    Dr. Min-Jeong Kim got her PhD degree in 2004 from the department of Atmospheric Sciences in University of Washington in Seattle. Her dissertation research involved computing single scattering properties of nonspherical snow particles using several electromagnetic scattering models such as the Finite Difference Time Domain (FDTD), the Discrete Dipole Approximation (DDA), and the T-matrix methods. She developed parameterization methods for single scattering parameters of dry frozen precipitation to support NASA GPM mission.

    Her research during her postdoc period (2005-2006) at NASA Goddard Space Flight Center included (1) developing a physical algorithm to retrieve falling snow particles over land employing space-borne millimeter-wave measurements, (2) developing parameterization methods to compute single scattering parameters of melting snow particles in a melting layer model, (3) developing combined algorithm using radar and passive microwave measurements to estimate precipitation, and (4) combining surface emissivity model and precipitation retrieval algorithm to support GPM mission.

    Between 2007 and July 2013, she worked as a Research Scientist of the Cooperative Institute for Research in the Atmosphere (CIRA) in Colorado State University. She was leading Joint Center for Satellite Data Assimilation (JCSDA) funded projects to assimilate clouds and precipitation affected microwave radiance data in NOAA NCEP NWP models. In addition, Dr.Kim served as co-chairs for JCSDA cloud and precipitation data assimilation working group during this period.
