Professional InterestsEver since airborne Doppler radar were recognized for their ability to depict the three-dimensional wind structure of the atmosphere in a way that can initialize tropical-cyclone simulations, the highest priority for Dr. Gamache has been the improvement of the automated quality-control, analysis, and transmission of Doppler data.
Dr. Gamache also leads the HRD radar group, which has the primary purpose of archiving and displaying the airborne radar data collected in hurricanes, evaluating their quality, and maintaining and developing software to quality-control, analyze, display, and transmit the data. The two most significant contributions of this software is improved automation, and the assistance to all who would use the data to improve basic understanding of tropical cyclones and other weather phenomena.
His primary interests are:
- Airborne Doppler observations of tropical cyclones and convective phenomena
- Assimilation of the Doppler observations in simulations of tropical cyclones
- Methods to improve automated quality control of airborne Doppler observations, including the structure of first-guess fields used to improve real-time de-aliasing
- Observing System Simulation Experiments, particularly those designed to optimize collection of airborne data
