The Fire Influence on Regional and Global Environments Experiment (FIREX) is a field campaign designed to understand and predict the impact of North American fires on the atmosphere and to support better land management to help prevent them from occurring.
Fires in the Western US are regular seasonal events that greatly affect air quality and climate through the production and direct release into the atmosphere of trace gases and particulates, and their subsequent chemical evolution and transport. A number of field campaigns and laboratory studies have been undertaken in recent years that have provided data on various aspects of emission products resulting from biomass burning, their chemical composition, chemical and physical transformation, and their eventual impact on air quality and climate.
Over the next 5 years, NOAA’s Chemical Science Division (CSD) of the Earth System Research Laboratory is planning to add to the available knowledge of atmospheric composition resulting from biomass burning by focusing on fires in the Western US. FIREX will span a variety of ground, mobile, and aircraft measurements, in addition to chamber and Fire Science Laboratory experiments.
