Improvements will include i) nitrate interactions with mineral dust and sea salt, using the thermodynamic equilibrium models EQSAM and ISORROPIA-II, ii) increase on the accuracy of the predicted nitrate aerosol size distribution by using the hybrid approach for aerosol dynamics, iii) explicit calculation of nitrate aerosol formation using the comprehensive aerosol chemistry model MECCA-AERO, iii) the use of a unified dust activation framework to account for the CCN activity of mineral dust coated with soluble aerosols (like nitrates) and iv) the use of the adjoint sensitivity technique to investigate the uncertainty of the CDNC predictions to aerosol number and hygroscopicity.
