Dr. Wang is a scientist at Earth Observing Laboratory (EOL) and The Institute for Integrative & Multidisciplinary Earth Studies (TIIMES) at National Center for Atmospheric Research (NCAR) in Boulder, Colorado. She received a B.S. in Atmospheric Science from Peking University, Beijing, China and a Ph.D. in Atmospheric Science from Columbia University, New York, NY. She served as a Post-Doctoral Research Associate at University of Colorado in Boulder, CO before joining NCAR in 1999.
Dr. Wang’s expertise is on climate observations and measurements, especially related to radiosonde observations, and on weather and climate variability. Dr. Wang has used global radiosonde data to create a 20-year global cloud vertical structure (CVS) dataset and analyzed the CVS data to study the characteristics and variations of CVS on a global scale. Dr. Wang started to work at NCAR in 1999 on developing a correction algorithm to correct humidity measurement errors from the Vaisala RS80 radiosondes. She has also done several other studies on sounding (both radiosonde and dropsonde) humidity characteristics, biases and impacts. She is in charge of data management (data quality-control and analysis) for all sounding data from field campaigns at NCAR. Dr. Wang has been and continues to be actively involved in developing a reference radiosonde system at NCAR. Currently she is also working on deriving a global, 2-hourly atmospheric precipitable water dataset from ground-based GPS measurements and using the data for various scientific applications, including monitoring the quality of global radiosonde humidity record and studying diurnal variations of atmospheric water vapor. She has authored and co-authored 25 peer-reviewed journal articles and 20 conference papers.
Dr. Wang has served on various national and international committees. Currently she serves as an Editor for Journal of Atmospheric and Oceanic Technology, on the Active and Remote Sensing Subcommittee for the NSF Facilities Assessment and as a member of the Working Group on Atmospheric Reference Observations of AOPC (The Atmospheric Observation Panel for Climate in GCOS).
