Goals: Find SOA yield for octane + Cl under high NOx condition (NO2 injected). Investigate volatility behavior based on 2D thermograms. Summary: Ammonium sulfate seed (0.01M,...

Many global models tend to produce a stratospheric polar vortex in the Southern Hemisphere winter that is too strong and too cold - a common issue known as the "cold-pole bias"....

Goals: Control (no NO2) for 20190718, which itself is a control experiment for the O3+NO2+H2O2 series -- this one with no H2O2, and therefore likely very little HO2 formation...
