| Summary: | We Abstract also use — the We TES use the special Tropospheric observations Emission during ARCTAS-B, in combination with a line-by-line radiative transfer model (LBLRTM), Spectrometer to (TES) explore to the determine potential the of TES concentrations to detect peroxy of the acetyl nitrate (PAN) and HCN within boreal smoke plumes. HCN is a gas-phase trace gases tracer CO, of O3, biomass NH3, and burning formic and acid is used (HCOOH) to separate within biomass burning CO from other sources (Holzinger et al., 1999). The primary boreal biomass NOx emissions burning from plumes. biomass We burning focus on are 22 rapidly plumes converted to PAN within biomass burning plumes (Alvarado et al., 2010). observed This PAN by can TES be transported between June over 15 large and distances July 15, and 2008 can as alter part ozone Section formation 2 describes far downwind the methods from the we biomass used to burning identify biomass source of (Leung the summer et al., 2007). Arctic Research of the Composition of the burning plumes using TES, retrieve NH3 and HCOOH within Troposphere from Aircraft and Satellites (ARCTAS-B) the smoke plumes, and calculate the spectral residuals in regions campaign. Only four of these plumes show evidence of of strong absorption by PAN and HCN. Section 3 presents the enhanced ozone, and even in these cases the enhanced ozone results of this study and Section 4 summarizes our preliminary may be due to intrusions of stratospheric air. We use TES conclusions and our plans for future work. retrievals of NH3 and HCOOH within the smoke plumes to calculate their enhancement ratios relative to CO. Our 2.
