Key Research Goals

  1. Relationship between NOx, NOy, HONO, p-NO3, PAN, VOCs, etc. and ozone (O3) in biomass burning plumes.
  2. Controls on PM/CO, BC/CO, aerosol absorption (σap)/CO enhancement ratios, aerosol chemistry and volatility properties in biomass burning plumes?
  3. Comparison of suitcase sampler Volatile Organic Compounds (VOCs) with Proton Transfer Reaction - Mass Spectrometry (PTR-MS).
