Data sets for: Contrasting Responses of Iron Acid Dissolution: Sulphuric Acid-dominates in the upper mixing layer vs Nitric Acid-dominates at the Ground-level

Data 1_Observational data: observed datasets for aerosol chemical species, total Fe (Fe_T), soluble Fe (Fe_S), and Fe solubility (�_S), and meteorological parameters (temperature & relative humidity) conducted in the upper mixing layer (DMS) and at the ground-level (Hangzhou).Data 2_IMPACT model results: major aerosol species (SO₄²⁻, NO₃⁻, NH₄⁺ and Ca²⁺), total Fe (Fe_T), soluble Fe (Fe_S), and Fe solubility (�_S) simulated by the Integrated Massively Parallel Atmospheric Chemical Transport (IMPACT) model.
