Project Background

This project established an ozone-monitoring program at Rice University with the goal of developing a better understanding of tropospheric ozone pollution.

The project acquired a station from which to launch balloons (ozonesondes) with payloads designed to acquire in situ profiles of ozone pollution.

Although ozone pollution is a significant problem in Houston, the Houston area has had no established program to monitor ozone concentrations at any altitude in the atmosphere above the surface. By measuring the vertical distribution of ozone as a function of time, we will be able to establish clearly the nature (local vs. transported) and extent and origins (industrial activity vs. mobile sources) of local ozone, thus providing an important step to finding solutions.

The establishment of regular profile measurements in Houston is an essential step to assessing issues of sustainability.

Project Update

Many publications have followed the original project research. In addition, further grants were obtained to continue research on the subject. Further publications based on the project data are forthcoming.
