Don Chambers, Ph.D
Research Scientist


Work

The primary focus of my research is quantifying and understanding sea level change, especially low frequency variations related to climate change. I use various satellite and in situ data to measure sea level, including satellite altimetry, satellite gravity measurements, tide gauges, and ocean temperature. I am particularly interested in using the various data to separate the thermal expansion and mass components of sea level rise.

Because satellite measurements have become very important in this type of research, I am also very involved in calibration and validation of the satellite sensors, especially radar altimeters. I am a member of the NASA Ocean Surface Topography, GRACE, and Interdisciplinary Science Teams.
