AIRTRAC v2.0: a Lagrangian aerosol tagging submodel for the analysis of aviation SO <sub>4</sub> transport patterns Open
Aviation-induced aerosols, particularly composed of sulfate (SO4), can interact with liquid clouds by enhancing their reflectivity and lifetime, thereby exerting a cooling effect. The magnitude of these interactions, however, remains highl…
