The challenge of creating historical weather products for the United States
Abstract: Historical gridded weather products are critical components in climate, hydrologic and ecologic applications.聽A large number聽of historical gridded data products exist, but many of these do not adequately account for various聽sources of uncertainty. We discuss statistical aspects of creating such estimates based on observational data and relevant techniques needed for a comprehensive product.

Dynamical Systems and Applied Mathematics at CU Boulder聽
I will discuss some of the areas of research of the faculty of the Department of Applied mathematics that are related to dynamical systems. A dynamical system is a 鈥渞ule for evolution on a set of states鈥�; essentially anything in which change is important. The theory of dynamics was born in the era of Poincare, but became much more exciting in the era of computers with the discovery of chaos by Lorenz and the realization that the geometry of most systems is fractal. I will discuss how these concepts impact our understanding of the meaning of determinism and of computability, and how chaos can be used in prediction, control, and design of dynamical systems.
