Oct 12, 2018 · The NASA Transport and Chemical Evolution over the Pacific (TRACE-P) comprised the third of three planned Pacific Exploratory Missions in the central and western regions of the Pacific Ocean basin. TRACE-P was part of NASA's Global Tropospheric Experiment (GTE).

Focused aircraft missions complement surface and satellite observations by providing detailed investigations of the dynamical and chemical processes affecting atmospheric composition over rather broad geographical regions. The March-April flight period for TRACE-P was selected after consideration of several factors [Jacob et al., 1999].

TRACE-P was designed to accomplish two objectives: 1) characterize the Asian outflow in terms of chemical composition over the northwestern Pacific, including quantifying the sources/emissions and 2) characterize the chemical evolution of the outflow, i.e., how the chemicals change as the airmass moves away from the continent, and assess the ...

The goal of the research is to understand the chemical composition of air masses in the TRACE-P study region through targeted analysis of selected organic trace gases and with exploratory studies of chemical composition of whole air samples using …

Sep 27, 2003 · A major event of transpacific Asian pollution was characterized through combined analysis of TRACE-P and MOPITT data. The TRACE-P observations showed that cold fronts sweeping across East Asia and the associated warm conveyor belts (WCBs) are the dominant pathway for Asian outflow to the Pacific in spring.

TRACE-P, conducted in March/April 2001, had as it's major objectives to 1) determine the chemical composition of the Asian outflow over the western Pacific in spring in order to understand and quantify the export of chemically and radiatively important gases and aerosols, and their precursors, from the Asian continent and to 2) determine the ...

This is an automated instrument that continually collects particles into a liquid and quantitatively measures, in real time, the soluble ionic mass concentration via a dual channel ion chromatograph.
