The loss of methanesulphonic acid (MSA) from stored ice cores can be significant over typical storage times, with diffusion to the ice-core surface controlling the loss. Methods for minimizing this loss are discussed and it is shown how measurements can be corrected by calculating the amount of MSA lost. A revised diffusion coefficient for MSA in solid ice, (4.1 x 10(-13)) +/- (2.5 x 10(-14)) m(2) s(-1), is derived to improve such MSA loss corrections.
