The Campaign

The Pacific Exploratory Mission (PEM) studied the long-range transport of tropospheric ozone, sulfur, and other trace gases over parts of the Pacific Ocean to understand the impact of human activity on atmospheric chemistry in that region. PEM had four deployments, each taking place over different parts of the Pacific Ocean between 1991 and 1999. Atmospheric gas samples were mainly collected by NASA’s DC-8 and P-3 aircraft, as well as through ground site instrumentation. PEM was carried out as part of NASA's Global Tropospheric Experiment (GTE).
