a Estimated 2-MT mass yield from the additional non-aqueous pathway for four different [OH]aq scaling factors. The x-axis is the modeled average daily [OH]aq concentrations at the SOAS and PRD monitoring sites. The data points are colored by the mean fraction bias (MFB) of the predicted daily 2-MT at those monitoring sites. Uncertainties for the OH radical concentrations are one standard deviation of the daily concentrations. Uncertainties of the mass yield are based on the Monte Carlo analysis assuming that the measured and predicted 2-MT from the multiphase phase formation pathway has a 20% relative uncertainty. b Predicted and observed daily average 2-MT concentrations along the cruise tracks (c).
