Paragraph starter
The accuracy of atmospheric simulations, particularly concerning natural emissions like sea spray aerosols, is highly dependent on the chosen parameterization functions. Research by Witek et al. (2015) demonstrated that different sea spray aerosol emission models can lead to significant variations in predicted aerosol optical depth over the Southern Ocean, underscoring the need for careful selection and validation of such models in any design project involving atmospheric or climate modeling.
