Frozen fraction measurements made using a droplet free-fall freezing tube apparatus are presented and used, with other recent laboratory measurements, to evaluate how well both the water activity idea and the translated meltingpoint curve idea of Koop et al. (2000) predict homogeneous freezing-point temperatures for aqueous ammonium sulfate and sulfuric acid solution droplets. The new freezing-point temperature data sets agree with the previous lowest temperature results for both solutes. The… CONTINUE READING
