Data of "Grain growth of ice doped with soluble impurities"

Optical microscopic images for the paper "Grain growth of ice doped with soluble impurities". Files noted with "raw" are the unprocessed images obtained from the microscope, while the ones unnoted are processed. Compressed files named "starting" are images for starting materials. Compressed files named by temperature are images for samples annealed at this temperature. In each compressed file, data are grouped by impurity concentrations.
