Use of Statistical Methods in the Analysis of Environmental Data

This article summarizes statistical analyses of three environmental problems: (a) the detection of trends in stratospheric ozone data using time series models, (b) the development of mathematical models to relate carbon monoxide concentration in Los Angeles to meteorological factors and traffic patterns, and (c) the study of changes in observed levels of carbon monoxide, lead, and sulfate that may be attributable to the introduction of catalytic converters on automobiles.
