Title: Large-Scale Computer Models for Environmental Systems
Author(s): Richard L. Smith*+
Companies: University of North Carolina
Address: , Chapel Hill, NC, 27599-3260,
Keywords: environmental modeling ; spatial statistics
Abstract:

Modeling of complex environmental systems is a major area of involvement of statisticians and applied mathematicians with disciplinary scientists. Yet it is also a prime example of differing emphases, with the applied mathematics approach focusing on deterministic modeling of the systems and the statistical approach focussing on utilizing the (often extensive) data for development and analysis of more generic stochastic models. Many problems involve combining information across a wide range of spatial and temporal scales. This talk, which will be based on the recently concluded program on this theme at the Statistical and Applied Mathematical Sciences Institute (SAMSI), surveys recent work on integrating statistical and mathematical modeling approaches. Examples exist in the fields of climate change, the spread of atmospheric pollution, and fluid flow through porous media.
