The goals of this experiment are to map out the chemical changes in the free troposphere as the atmosphere transitions from winter to spring. It is hoped to begin to understand the chemical conditions that influence the lifetime of ozone and understand more about the productivity of this region of the atmosphere with respect to the in-situ production of ozone. How the free troposphere responds to changing levels of pollution could be critical to the development of future abatement strategies.
