Fig. 5: Comparison of aerosol Fe solubility (%) from multiple field campaigns for the field data and from the simulated estimates.

For the comparison with the observational data set (a), the daily model estimates along the cruise tracks during each sampling month were taken from each model estimate of b the IMPACT model, c TM4-ECPL, d CAM4, and e GEOS-Chem. Only the simulated data for which maximum likelihood estimates (MLEs) of total Fe concentrations fall within ±2 σ0 of the measurements were used for the comparison with field data.
