Airborne Measurements of Formaldehyde Employing a Tunable Diode Laser Absorption Spectrometer During TRACE-P
ABSTRACT
This final report summarizes the progress achieved over the entire 3-year proposal period including two extensions
spanning 1 year. These activities include: 1) Preparation for and participation in the NASA 2001 TRACE-P campaign using
our airborne tunable diode laser system to acquire measurements of formaldehyde (CH2O); 2) Comprehensive data analysis
and data submittal to the NASA archive; 3) Follow up data interpretation working with NASA modelers to place our ambient
CH2O measurements into a broader photochemical context; 4) Publication of numerous JGR papers using this data; 5)
Extensive follow up laboratory tests on the selectivity and efficiency of our CH20 scrubbing system; and 6) An extensive
follow up effort to assess and study the mechanical stability of our entire optical system, particularly the multipass absorption
cell, with aircraft changes in cabin pressure.
