Have added the 2 divisions for global model and 6 divisions for defence models. Division detail now in name and descriptions given. No mention of bins as these relate to the model. Please check carefully as to the sizes. Please let me know if description reads correctly and if any other information is required. I would like to link these to the stash codes, however, there is only 6 stash codes, so not clear if these only link to the 6 defence divisions??? https://reference.metoffice.gov.uk/um/_stash see Dust division 1 mass mixing ratio (1-6). In addition, need to check any current usage of 0-13-193 and 0-13-194 will be effected by the change in name to include the sizes
