Laboratory experiments explored the sorption behavior of SO 2 on ice between the temperatures of −30 and −5°C and with SO 2 mixing ratios of 15 to 95 ppb. The time‐dependent data show clear evidence of two distinct exponential time constants and a dependence on SO 2 concentration. The equilibrium amount of SO 2 retained by the ice, determined by integration of the kinetic data, was found to increase strongly with temperature. The experimental results may be interpreted in terms of a disordered surface region which increases in thickness with temperature, enlarging the storage reservoir and generating the observed temperature dependence.
