4th PAM Users Meeting

The 4th PAM users meeting will take place on Thursday evening, October 20 at 6:00 PM in Room A106 of the Oregon Convention Center at the upcoming AAAR meeting. If you or members of your group plan to attend, please let me know (if you have not already done so): http://doodle.com/poll/pfcukfyry4hfex3g.

Agenda (updated 6-Oct-2016):

Talks:

1. Andy Lambe - Welcome and overview of recent publications using the PAM oxidation flow reactor

2. Jay Slowik - Comparison of PAM and chamber-generated SOA using extractive electrospray ionization time-of-flight mass spectrometry

3. Jimenez Group - Recent results from our OFR work: Zhe Peng on kinetic modeling (NOx, spreadsheet, new Igor code, regions of operation); Ben Nault on RTD comparisons, Brett Palm on LVOC fate correction model and NO3 OFR, Pedro Campuzano-Jost on OFR in aircraft, Weiwei Hu on H2SO4 sensitivity study

4. Shantanu Jathar - Measuring and Modeling Photochemical Production of Organic Aerosol in an Oxidation Flow Reactor from Diesel Exhaust

5. Hilkka Timonen - PAM chamber in emissions measurements

6. Provat Saha - Distinct Seasonal Differences in Secondary Organic Aerosol Formation from In-situ Oxidation of Near-highway Air.

7. Simone Pieber via Jay Slowik - Gasoline Vehicle Emissions Aged in PAM and Smog Chamber

8. Andy Lambe - Updates on Aerodyne PAM Oxidation Flow Reactor: Overview, Best Practices, Ongoing Developments

Potential Discussion Topics:

- Gas/particle partitioning timescales in the PAM and how they influence SOA yields and interpretation of those yields for the atmosphere.

- Acceptance vs. skepticism of PAM in the aerosol science community

- "Open Mike" Time
