Short summary

Laboratory studies examined carbonyl deposition into ice crystals using a flowtube setup. Ice crystals were grown under conditions that mimic cirrus clouds in the presence of carbonyl vapors. Ice and gas samples were collected and analyzed to calculate ice uptake coefficients for 14 carbonyls at different temperatures. This revealed an inverse relationship between uptake and temperature. Vapor pressure and molar mass were found to be the most significant factors in uptake.
