  1. Definite Paper Topics: Draw-down of CO2 and OCS (Vay, Blake) CO2/CO ratio as a tracer of Asian pollution (Yonghoon Choi) Top-down emission estimates of CO using MOPITT, AIRS and aircraft measurements. (Turquety, Pfister, Warner) Top-down emission estimates of NOx using SCIAMACHY and aircraft measurements. (Martin) Top-down emission estimates of formaldehyde using SCIAMACHY and aircraft measurements. (Millet) Regional emissions inventories as compared to observed data (Carmichael) Formal inversion for CO, NOx and speciated HCs. (Carmichael) Source-receptor transport characterization using trajectory models and satellite data (Warner, Pierce). Non-marine sources of methyl iodide (Blake, Wingenter) Source variability in CH4 (Bartlett, Sachse, Blake)

  2. Helpful research tools: Stratospheric tracer: CH4, O3, CFCs, 7Be, H2O, PAN/HNO3 ratio (Dibb, Blake, Avery, Sachse, Moody) Oxalate, acetonitrile and other measured components as biomass burning tracer (Blake, Dibb?) MBL tracer: Bromoform, methylene bromide, methyl iodide (Blake) Tracer specific to power plant emissions: SOx etc. (Weber? – keep P3 data in mind) Source quantification for particulates: biogenic v. anthropogenic, fossil fuel v. biomass. (Weber, Clarke – given help with flight-leg categorization from chemical tracers etc.) Modeled airmass tracers along flight tracks. (Carmichael, Jacobs) Modeled mixing diagnostics for merged data set (Pierce)

  3. Topics for collaboration: Lightning as a source of NOx (make sure to communicate with lightning/convection working group) NH4 sources and relation to neutralization of aerosols. (Keep in mind link with P-3) Observations characterizing pure BB plume and its impacts on BL measurements. (DC8 fast-response instruments may have data – esp 7/18 flight) – Deferred to biomass burning working group MBL sources: their relative importance in convective and WCB mixture) – Deferred to photochemistry working group. Source quantification for particulates. - Deferred to aerosol working group. – Provide gas-phase chemical tracers.
