This directory contains a code that was used to run model simulations described in section 3 of the manuscript (eulag.iles.activation.con_S.csh and input.dp.dat), data files written during the simulations (fort.9.* files; lg/sm is for small/large CCN, 0.333/1/3mps is for different mean updraft velocities (meters per second, mps) and program used to creates plots in Figs. 4 and 5 (plot.S_rad.* and plot.width_actfra.*; the first is for the mean supersaturation and mean radius; the second is for the mean spectral width and fraction of CCN activated. simulation code and input data file: eulag.iles.activation.con_S.csh input.dp.dat data from simulations: fort.9.lg.20.1mps fort.9.sm.20.1mps fort.9.lg.20.3mps fort.9.sm.20.3mps fort.9.lg.20.0.333mps fort.9.sm.20.0.333mps analysis and ploting codes: plot.width_actfra.lg.color.for plot.width_actfra.sm.color.for plot.S_rad.sm.color.for plot.S_rad.lg.color.for
