Biography

Yoo-Jeong Noh received his BSc in Atmospheric Science from Yonsei University (1997) and MS in Environmental Engineering (Environmental heat transfer/fluid mechanics) from Pohang University of Science and Technology (1999). From 1999 to 2001, she had professional experiences on precipitation analysis using TRMM and surface observations, and numerical modeling (WRF and MM5) while working at the Meteorological Research Institute/Korea Meteorological Administration and the Global Environment Laboratory/Yonsei University in Korea. After receiving her PhD degree in Meteorology from Florida State University in 2006, she joined CIRA and continues to work on satellite precipitation measurements and mixed-phase clouds as a Research Scientist following her two year postdoc research. Her areas of research interest include developing precipitation algorithms using active/passive microwave satellite data and surface observations, radiative transfer modeling, and studies on mixed-phase clouds using satellite and aircraft observations.

Recent Work

The goal of this study is to develop a snowfall retrieval algorithm based on Bayes’ theorem using high frequency microwave satellite data over the Great Lakes region. An important component of the Bayesian algorithm is the a-priori database that connects brightness temperatures to snowfall rates. In constructing this database, we used a large number of snowfall profiles observed from both satellite (CloudSat) and surface radars (NEXRAD) In the radiative transfer calculations, atmospheric sounding profiles and liquid water information in clouds are obtained from aircraft measurements during the C3VP/CLEX-10 field experiment and WRF simulations. In addition, the scattering properties of the snowflakes are used from the calculations based on realistic nonspherical shapes using discrete dipole approximation. The retrieval algorithm is applied to AMSU-B satellite data for snowfall cases in the Great Lakes region during 2006 and 2007 winter seasons.
