| description | The Focused Isoprene eXperiment at the California Institute of Technology
(FIXCIT) was a collaborative atmospheric chamber campaign that occurred
during January 2014. FIXCIT is the laboratory component of a synergistic
field and laboratory effort aimed toward (1) better understanding the
chemical details behind ambient observations relevant to the southeastern
United States, (2) advancing the knowledge of atmospheric oxidation
mechanisms of important biogenic hydrocarbons, and (3) characterizing the
behavior of field instrumentation using authentic standards. Approximately 20
principal scientists from 14 academic and government institutions performed
parallel measurements at a forested site in Alabama and at the atmospheric
chambers at Caltech. During the 4 week campaign period, a series of chamber
experiments was conducted to investigate the dark- and photo-induced
oxidation of isoprene, α-pinene, methacrolein, pinonaldehyde,
acylperoxy nitrates, isoprene hydroxy nitrates (ISOPN), isoprene hydroxy
hydroperoxides (ISOPOOH), and isoprene epoxydiols (IEPOX) in a highly
controlled and atmospherically relevant manner. Pinonaldehyde and
isomer-specific standards of ISOPN, ISOPOOH, and IEPOX were synthesized and
contributed by campaign participants, which enabled explicit exploration into
the oxidation mechanisms and instrument responses for these important
atmospheric compounds. The present overview describes the goals, experimental
design, instrumental techniques, and preliminary observations from the
campaign. This work provides context for forthcoming publications affiliated
with the FIXCIT campaign. Insights from FIXCIT are anticipated to aid
significantly in interpretation of field data and the revision of mechanisms
currently implemented in regional and global atmospheric models. |
