Specializations and Research Interests
Dr. Kuhn's early research concerned the radiative properties of the Earth's upper atmosphere, how infrared radiation is transferred in a medium in non-local thermodynamic equilibrium. He was one of the participants in the Climatic Impact Assessment Program to evaluate the potential effect on climate of supersonic transports in the early 1970s. In the mid- and late-70s, his research was primarily devoted to studies of planetary atmospheres, e.g., how photochemistry influences the composition of Jupiter's atmosphere, the climate of Mars early in its geologic history, and how the Martian environment would affect, and be influenced by, terrestrial organisms. In the 80s, Dr. Kuhn's research was devoted to studies of Earth's climate with relatively simple radiative convective models but also the NCAR Community Climate Models. Most of his research in the 90s concerned the climate of the very early Earth extending back 4 billion years ago when solar radiation, atmospheric composition, land fraction and rotation rate were much different than they are today. His present research concerns the effect of the changes in the amount of non radiative gases in the atmosphere on temperature and the latitudinal temperature gradient.
