Dr. Chao received his Ph.D. from Princeton University in Atmospheric and Oceanic Sciences. His research interests include satellite oceanography with a particular focus on coastal oceans; ocean modeling, data assimilation and forecasting; interdisciplinary science of coupling ocean circulation with ecosystem and air-sea interactions; and climate variability and change.

Dr. Chao explains how satellite technology has evolved throughout the years to deal with the challenge of measuring ocean salinity from space. He points out that early experiments conducted by the Jet Propulsion Laboratory yielded little in the way of usable data, but this process allowed engineers and researchers to make adjustments and try their experiment again.

Applicable Science Standards
  • Developing and Using Models Developing and Using Models. A practice of both science and engineering is to use and construct models as helpful tools for representing ideas and explanations. These tools include diagrams, drawings, physical replicas, mathematical representations, analogies, and computer simulations.
  • Analyzing and Interpreting Data Analyzing and Interpreting Data. Scientific investigations produce data that must be analyzed in order to derive meaning. Because data patterns and trends are not always obvious, scientists use a range of tools - including tabulation, graphical interpretation, visualization, and statistical analysis - to identify the significant features and patterns in the data. Scientists identify sources of error in the investigations and calculate the degree of certainty in the results. Modern technology makes the collection of large data sets much easier, providing secondary sources for analysis.
  • Using Mathematics and Computational Thinking Using Mathematics and Computational Thinking. In both science and engineering, mathematics and computation are fundamental tools for representing physical variables and their relationships. They are used for a range of tasks such as constructing simulations; solving equations exactly or approximately; and recognizing, expressing, and applying quantitative relationships.
