Chia-Wei Hsu is an associate scientist at the Physical Sciences Laboratory of the NOAA Earth Research Laboratories in Boulder, CO. Chia-Wei previously worked on model validation for his two post-doctoral projects. One focuses on the tropical sea level variation bias in the current ocean general circulation model (GCM), a collaboration between the University of Arizona and the NOAA Geophysical Fluid Dynamics Laboratory. One focuses on the ocean surface flux bias at intraseasonal time scale in the coupled GCM, a collaboration between Colorado State University and the University of Reading. His interest is to create useful analysis tools by taking advantage of open-source software to better understand related scientific issues. He is working with Cathy Smith and Mike Alexander on data management and developing a visualization/data portal.
