A tempting approach to investigate the link between cosmic rays and climate is to explore Forbush decreases - sudden drops in the amount of galactic cosmic rays reaching Earth, caused by large Coronal Mass Ejections from the sun. Due to the sudden nature of these events effects from other solar parameters, such as total irradiance or UV can be ruled out. There has previously been several papers using observations to gauge the impact of Forbush decreases on cloud cover, but with no definitive conclusion. In this study we model the response of the optical parameters of marine aerosols – precursors for cloud drops. We are specifically looking at the Angstrom exponent and the optical thickness. The goal is to elucidate the sensitivity of the type and magnitude of response in these parameters during a Forbush decrease, to changes in aerosol production, condensable gases, and primary aerosols.
