The Campaign
The Pacific Exploratory Missions (PEM) studied the long-range transport of tropospheric ozone, sulfur, and other trace gases over portions of the Pacific Ocean to understand the effects of human activity on the atmospheric chemistry in that region. PEM had four deployments, which each took place over various parts of the Pacific Ocean between the years of 1991 and 1999. Atmospheric gas samples were primarily collected by NASA’s DC-8 and P-3 aircraft, as well as via ground site instrumentation. PEM was conducted as a part of NASA's Global Tropospheric Experiment (GTE).

The High-Performance Liquid Chromatograph (HPLC) is an in situ ground-based analyzer that is used to separate and identify components within a sample of air or mixture. It achieves this by injecting a liquid within the sample causing different flow rates for each component as they flow out of the column. As each component exits the column, their concentrations are measured at a high resolution. In Earth science research, HPLC is typically used to determine various trace species in the atmosphere such as formaldehyde, hydrogen peroxide, and volatile organic compounds (VOCs). HPLC is commonly used for laboratory analysis and ground-based measurements, but it can be used for airborne measurements as well.
